Facial Detection Camera Switching

It would be great if there was a way to add face detection and auto camera switching for PC option to the Manycam app. It would also save so much time in post editing because the stream video will have switched to the camera I was looking at. I am currently looking for a macro solution automated of course.

Something like this would be awesome!
I have two cameras that I use when teaching (one when I’m sitting at my PC, one on a whiteboard) and I have two presets (one for each camera, with the other as PIP)
If I could have it switch between the presets as I stand up and sit down, it would be one less thing to worry about!
