This would allow the user to have the committed section be delivered on to the same existing track on a new playlist. This would be helpful for playlisting ideas with different plugins, mix options, as well as saving other versions. Example: I do this currently with my drums. When I phase align certain channels after comping I like for the new tracks to be on the same track but different playlist. So I might have "Kick In" followed by "Kick Out Phase Aligned" -- currently I have to commit the Kick Out track to a new track, then create a new playlist on the current track, then drag the region to the new playlist.
This would save a ton of extra mouse clicks.
Attached is the commit dialogue box.
