A feature request for screen sharing

I was thinking about this for a long time. I have 2 monitors so what if we would be able to share multiple screens at the same time like the active live window will be based on where the cursor is. For example there are 2 screens (Screen 1) (Screen 2) and if the streamers cursor is at screen 1 other people will see screen 1.Dont know if it would work but kinda helpful
