I want the items to stay coherent in time across the tracks so I can still edit them as a group, but I got an idea.
Maybe a macro nudge position right->nudge right trim left->nudge left trim left will do the trick
Never mind... these actions don't exist and save nudge dialog settings doesn't help much either.
At least this is a quick and simple manual solution with three steps per track. Better than nudge->select next take for hundred of take snippets
