Please develop a feature to receive a pop up warning when the program only hears 1 voice during couples therapy sessions

s there a way to have your program alert me if it only hears 1 voice, when it is supposed to be for couples therapy? Sometimes I forget to choose the correct microphone to listen from and it only captures my audio. I would like to have a message pop up which informs me that there is a problem, before I allow the entire session to pass with none of the client's part of the conversation recorded.
