Listing multidisc albums with different composers

I'm not aware how to change the multi-value separator, but if you don't want a field to be split automatically (and therefore accept semicolon as text) you just need to modify the field list under:
Preferences -> Advanced -> Display -> Properties dialog : Multivalue fields

By default it's 'ARTIST;ALBUM ARTIST;COMPOSER;PRODUCER;PERFORMER;GENRE'

Obviously if your tags have already been split this won't fix them, so you'd need to run something like a Masstagger action against them:
'Format value from other fields', ALBUM ARTIST, $meta_sep(ALBUM ARTIST,'; ')
Which will replace multiple fields of ALBUM ARTIST with a single field separated by '; ' in this example.

Obviously test on a sample.
