Let me explain. 

I'm working on an arrangement of a video game composition for an upcoming tribute album. I have imported the original track into my project session on its own Audio Track. I have all of my MIDI instruments in their own folder. With Exclusive Solo selected, I would like to be able to press the solo button on the audio track to only hear the original track's audio, and then press the solo button on the MIDI folder to only hear my arrangement. However, as it is now, pressing the solo button after one or the other is already pressed doesn't mute the other tracks. I would like to quickly switch between soloing all tracks in a folder, and soloing just a solo track not contained in that folder.
