Delete muted notes

Hi all,
 
Working in PRV most of the time. I would like to be able to give a region of notes a 'time out' so that I can try something else. Then I try my something else and can decide whether I like the new thing or the original thing better. Right now I'm muting my region of notes by Alt-Right-clicking them. This works fine, but I can't figure out how to get back from that without the crude Undo. How in PRV can I say "select only the muted notes" so that I can then either un-mute them or delete them? Right now, if I prefer my new idea, it usually sites right on top of my muted idea, making it impossible to select between the two.
 
Can I select the notes I have muted as a group? And please don't tell me to go to Track View and confront the Balrog that is Track Layers. That way lies certain death; it is folly. 

Thanks for the suggestion. The only problem with that method (which I've attempted) is that since the two tracks point to the same synth source, I can't mute one track and not the other. I have taken to creating a dummy track with a different but similar instrument on it just for this purpose, but after all this it seems like I'm pulling my left ear with my right hand. There's got to be a simpler way......Doesn't there?
