Thought about sthg similar, however, this suggestion can only work with the first track of an album,
meaning after renumbering all tracks, you just keep 01 number track in list,
and by reusing the renumbering function,
assuming you have 1 folder / 1 disk, you get a incremental value of your disk for each folder.
it is not possible to automatically copy that value on each track of the folder after this.
on the other side, Mp3tag is the best tool ever made for tag management, and the function of export / import values creates infinite ways to get solutions.
