Any way to latch " view selected notes" in PRV

Ok - not sure if I can explain this clearly, When you "view velocities of selected notes " in the Piano Roll view, in essence to isolate a single note , I like to select all like notes via the graphical keyboard to edit all closed hats for example. You select a velocity bar to edit - all the other notes velocity bars disappear ( because you are re-selecting the single note instead of the note through out the whole track.)  I lose reference to the other notes. Kind of defeats the purpose for me. Is there a way to keep the view velocities of selected notes " latched " so to speak -  so you can edit that single note though out the whole track. The only other method is to cut the single note to a new track - edit - then re-paste. Or is there a more efficient way to isolate a single note through out the track for velocity editing ?
