@dangollayan - I will refer you to the implementation guide of QnA available at https://docs.aws.amazon.com/solutions/latest/qnabot-on-aws/welcome.html, and more specifically the following two sections:
https://docs.aws.amazon.com/solutions/latest/qnabot-on-aws/architecture-details.html#amazon-lex-web-client
and
https://docs.aws.amazon.com/solutions/latest/qnabot-on-aws/configure-intent-and-slot-matching.html
this has in fact and example similar to your case and in addition, the notes and consideration explains that
"To take advantage of the additional features supported by Amazon Lex, such as confirmation prompts and regular expression to validate the value of a slot, you can also create the Amazon Lex intents and slot types in the QnABot Lex bot using the Amazon Lex console. For more information, refer to Adding intents in the Amazon Lex V2 Developer Guide.

Even if the Amazon Lex intents and slot types are created in the Amazon Lex console (created outside of the QnABot designer), you can reference any SlotType defined in the bot in a QnABot Item ID, and also map a QID to a manually created Amazon Lex intent in QnABot on AWS."
I hope this helps.
