The Content Mask Should Affect Some More Operations

quite often I have the necessity of moving some content up or down in a track. this can be easily done using commands such as the “insert new row in track” (with INS key on keyboard) or "delete whole row in track (BACKSPACE).

however, this kind of commands do not take in count the Advanced Edit’s Content Mask when executing. It would be extremely helpful if they would, so you could shift volume commands up and down in a track, for example, but the possible usages are lots.
