Feature request: mute all streams but one

[Hotteterre]

Hello, thank you for the great work! Personally, I appreciate a lot the possibility to mute/unmute audio streams with a click. But could be possible enabling the possibility to mute all the others streams except a single one (or a whitelist of 'authorized' streams, maybe associated to a particular profile)? I'd find it particularly useful to automatically exclude unwanted sounds - as system notifications - when listening to music, watching a movie, during video conferences or in other analogue activities.
Thank you!!!

How would you go that feature?
How would a user mute all other streams (as opposed to the current one)?

@aleho, thanks for your reply! I'm only a simple user, and cannot figure if it's technically possible, but I was thinking to a submenu associated to every stream, from which select to mute all others streams.
Please, excuse me if I wrote nonsenses. Thank you for all!
