I love mp3tag, and it's currently helping me cleanse and correct my music library. Quite a therapeutic process! However, one or two things seems like they should be do-able, but I can figure out how.

I have various one off tracks, EPs, albums, compilations and so on in my library. There is a mixture in how the track numbering and disc numbering has been tagged within these files. For example, the track/disc numbering could be any of the below:

1, 2, 3, 4, 5
01, 02, 03, 04, 05
001, 002, 003, 004, 005
1/5, 2/5, 3/5, 4/5, 5/5
01/05, 02/05, 03/05, 04/05, 05/05​

Is there a way to unify this into a single numbering system? So, for example, I highlight a bunch of tracks and run an action to change all the numbering of tracks to 1, 2, 3, 4, 5, where it retains all the numbering, just puts them in the format I want?
