Bug 474635

This is a feature request (as I cannot figure out how to do with import from tags / regular expressions or an elegant search/replace that is not number by number).

Specifically for classical music albums, it would be great to be able to change Arabic and Roman numeral part numbers. Example:

Symphony No. 5 in C major: 1. Allegro 
Symphony No. 5 in C major: 2. Adagio
Symphony No. 5 in C major: 3. Scherzo
Symphony No. 5 in C major: 4. Finale

would become:
Symphony No. 5 in C major: I. Allegro 
Symphony No. 5 in C major: II. Adagio
Symphony No. 5 in C major: III. Scherzo
Symphony No. 5 in C major: IV. Finale

Note that titles without the work name in the tag should also work:

3. Scherzo -> III. Scherzo

(And if there is an elegant way to extract this from tags, I would love to do it that way.)

It would be great to go in either direction. (A->R or R->A.)

Thanks!
