I know how to show multiple tracks in a single piano roll (where the other tracks are ghosted in the background), and I know how to show single tracks in multiple piano rolls (which seems to be the default behavior), but is there a way to have each piano roll window show a different track?
 
When I select a track in one of the piano roll windows it seems to update all the other piano roll windows to match.  I would like to have separate tracks in each.
