Here is my solution to how PT handles this(which can be a PITA). I add a pre-fade send to every track, in the last slot. Then I mute all of them(Alt-mute any send and all in the row will mute). I assign that send to an extra set of outputs, which I name SoloPath(just makes sense to me). That set of outputs feeds another input of my monitor switcher. This way, I can Ctrl-click on the send for any track(or combination of tracks) select the source to go to my monitors so I can listen to anything(even an AUX track fed by post-fade sends) totally independent of anything else going on
