Flac tags, missing and/or duplicate tags

I would use a mapping to map ALBUM ARTIST to ALBUMARTIST.
See Options Ctrl-O Tags>Mapping.

How to map ALBUMARTIST TO ALBUM ARTIST for flac files

Could someone please briefly walk me through how to create a mapping that will cause any edits I make to the ALBUMARTIST field in a FLAC file to also apply to the ALBUM ARTIST field? I'm having an issue with the way Media monkey is interpreting these tags and this seems the fastest way to fix the issue. Thanks.
