So yeah, as you point out, this is an area that hasn't been fully developed.
There are pieces of what you want such as if you do specify tmp2 and don't specify dst then your configured tmp2 will be used for both tmp2 and dst. But, that only works for a single tmp2.
I don't have particular plans to address the shortcomings of tmp2 right now so I'll put out a few questions and comments that may or may not lead to a useful discussion about improving your situation. Or, perhaps they will just help me understand how multiple tmp2 support should work. I also think your setup may be a bit different than the ones I have worked with mostly so hearing about it would help me think it through better.
As chiapos (the Chia Network plotter) has improved its tmp usage has declined. Also, with madmax you end up with fewer parallel processes and thus less overall tmp usage at any given point. This has made the need to get plot processes off of tmp quickly much less important. I would have expected that with HDD (rather than NVMe) plotting that there would be even less of a crunch on tmp space. Though I guess with HDD plotting you might want only one process using a given HDD (or RAID set) to avoid some head thrash. Can you say a bit more about your situation that causes you to be limited by tmp space?
dst drives end up often being used to specify the final resting place for plots, though really archiving is the best tool for handling plot distribution. When using archiving, dst acts as a buffer.
Anyways, could you share your full config and explain what type all the drives are and any other commentary to help me understand your setup? Thanks.

HP Proliant Gen 9; 56 total threads (28 cores; 2x 14), 128GB RAM.
If madmax had existed when I configured this setup, I'd have bought something else altogether, true.
Yet here we are, with 2x NVMe (1,9 TB (1.920.383.410.176 bytes) each), same sized 2x SSD and for now a volume of 4x 16TB HDD also for plotting (until the other 8x 16TB HDDs have filled up).
I plan on replacing 1 or 2 SSDs with 1 or 2x 4TB NVMe.
I've been trying to tune / tame plotman for weaks now :( As we speak I'm once again testing 3x k33 plots on each NVMe/SSD. I'll know more tomorrow if my current configuration below will work :)
But for now, I have temp limitations that no more than 3 tasks may run before phase 4, step 0. This is squeezing the available free space to the max. Off-setting some of that data to the quick HDDs would give that extra margin; I might even use 3:6 instead of 4:0! Currently, as preparation for my 4TB NVMe's, I'm using 2 temp folders on my 4-disk HDD volume; each will get 3 plots (this will test RAM/CPU bottlenecks). I'm ALSO using that same 4x HDD volume already as a TEMP 2. I don't see any delays for plots on that volume so the HDDs can handle it.
That said, at some point the 4x HDD volume will be converted to 4x HDD for plot storage. Especially then, having the temp -2 folder point to the destination HDD would make for a smooth run, I hope. That said, you'll have to leave enough space for that temp-2, so if there's only space left for 1 or even 2 plots on the destination HDD, that HDD shouldn't be used any longer as a -2 temp folder. Filling the disks to the max would be a manual exercise then, in my case. That would work for me :)

# Archival configuration. Optional; if you do not wish to run the
# archiving operation, comment this section out. Almost everyone
#
# As of v0.4, archiving commands are highly configurable. The basic
# configuration consists of a script for checking available disk space
# and another for actually transferring plots. Each can be specified
# as either a path to an existing script or inline script contents.
# It is expected that most people will use existing recipes and will
# adjust them by specifying environment variables that will set their
# system specific values. These can be provided to the scripts via
# the `env` key. plotman will additionally provide `source` and
# `destination` environment variables to the transfer script so it
# knows the specifically selected items to process. plotman also needs
# to be able to generally detect if a transfer process is already
# running. To be able to identify externally launched transfers, the
# process name and an argument prefix to match must be provided. Note
# that variable substitution of environment variables including those
# specified in the env key can be used in both process name and process
# argument prefix elements but that they use the python substitution
# format.

Have you tried putting the pair of matched NVMe in raid0 and used that with madmax and a 2:0 phase with limit of 1 phase stagger of 2:0 and limit of 1? comment out tmp2 and dst. plotman will archive from tmp then. After running piles of chiapos processes, when I switched to madmax I ended up with this setup on one system and close to it (added a ramdisk tmp2) on another that had more RAM.
What sort of numbers do you have for TB-of-plots/day in the various setups you have tried?
If you are buying more fast disks, consider more, smaller, matched ones. This generally increases bandwidth and you can raid0 them to use that increased bandwidth with fewer processes and drives to track. Though, it's not obvious that you need more fast disk vs. some RAM perhaps. Or maybe no new hardware.
What make/model are the pair of 2TB NVMe?
from plotman.
Madmax wouldn't have use for that much space? And I'll be using some i9's with 128GB RAM for my k32 plotting needs.
For my current results... I'll have to come back to that in a few days. I just went to a global stagger of 81 mins (down from 93), it will need another 12 hours or so to catch up to this new rhythm. I have to move real slow changing settings, it escalates quickly :)
PS: any Ubuntu solutions to see a history of free disk space? netstats had a 3rd party plugin, but gotta figure that still out :)

2x NVMe:

I've been using plotman+prometheus+grafana to monitor various resources. But yes, the point of madmax is to get the same or better throughput with fewer processes. This means less temp space and less ramp-up time to respond to configuration changes. I ended up with three processes at a time on each system based on the phase stagger mentioned above.
A quick look suggests that your system should be better than the server I had. Mine managed about 3TB/day with chiapos (21 processes iirc) and up to 5TB/day with madmax (phase1 stagger resulting in 3 processes). It was a dual Xeon 2690 with total 16-cores/32-threads. The madmax numbers were admittedly with a ramdisk for tmp2, but I don't recall that being a really big change, though nice.
from plotman.
Current results are about 15 k33 plots for the last 24hours of finished plots. On average, a plot takes 21 hours (starting at 17 with the very first plots). I have room for more; CPU is not maxed out, nor is RAM or even disk freespace. But again, a setup like this needs very careful tuning :(
