The example showed using a RealTrack not in the current style but what if I want to change bars in one of the tracks in the current style?

And why did this process appear to automatically remove the RealTrack for Mandolin? Maybe I wanted that track but just needed a few bars changed?

What happens if I want to change more bars in the same track?

What happens if I want to change bars in several tracks?

Am I supposed to go and clean up the DragDrop folder? It leaves all the tracks in there so I'll have quite a mess in there pretty soon.
