Feature Request: Automated volume adjustment when changing sources

Hi, I don't know if there is already a way to do this, but I'd like to suggest a feature where a user can pick a "base" volume level that you always start out at. 

Use Case:  Have my system connected with a TV so volume levels often need to be higher.  When I switch over to Tidal, the music is just blaring.  Hard to remember to turn it down when you change sources.  Would be great to have a base level of volume you can always revert to when you change inputs (TV watching via streaming service to listening to music on different content provider).  

If I'm missing something in the settings, someone please set me straight!  Thanks!
