For editing multiple drum tracks I would love a special split function that would be like a diagonal cut, but maybe it could be even cooler than that.

I would like a scrip that when tracks were grouped, you could hit "split special script" key. Then it would split the first track in the group right wehre you hit it, but each track after that would split a user defineable amount later, and add up to each other to make a nice diagonal cut. Is this doable?
