[Feature Request] NPS MFA with number matching

So I have an environment setup with RD Gateway for users to RDP through and receive a notification to approve or deny the login.

I great add on would be to have those notification accept number matching, but as RDP can't display additional dialogues, I want to suggest a substitute. A need to enter the OTP into the notification before allowing access.

I'm not sure if that's possible currently so I'm submitting it as a Feature Request.
