you can:
double click on the tracks clip - this opens up that track in the PRV
you can also open up an instance for that track, right click on the dock icon and select "lock contents".
this will let you open up multiple instances of the PRV for different tracks if you choose.
but what I do is use the PRV's synth view built in to the PRV. lock the tracks you don't want to edit, un lock when you do. you can also show/hide their content just by pressing a button.
this way everything is right at your finger tips.
