How do I incorporate Disk # into my naming scheme?

I've got a few boxset I'd like to rename in the following format

Artist - Album - Disk # - Track - Title.mp3

I've got all my music with an ID3 field for Disk # that is correctly labeled (1-4), but I can't figure out how to use that information in MP3Tag to rename the files.

Just use the name of the field with the converter :mt_ttf: Tag - Filename.
