Allow "In library" icon on Discography view to toggle "In library" and "Not in library"

I tried finding a similar request, but i think it slipped under my view.
So, i blame the forum based request handling if this is already mentioned.

When i view an artists Discography i often use the “in library”-icon so se which albums i have aquired/added. But it would be great if the control could behave like Focus features, which means i could view the albums/releases which is not in my library.

I’m not sure if this is a request for Focus features in other views possibly?
