I searched the forums and found this action example for copying data from one field to another (in this case AA to A):
Action type: Format value Field: ALBUMARTIST Format string: %artist%
Is there a way I could append to the new field instead of overwriting? I would like to append at the beginning, prefixing.
EDIT: DUmmy me, I found it.
It should be like this, right? (although the fields in this example make no sense )
Action type: Format value Field: ALBUMARTIST Format string: %albumartist% (%artist%)
