Easiest way to rename a flac tag?

To rename a flac tag I can copy it to the new tag (format value) and then do a remove tag of the old one. But is there a single action that can just rename the tag?

No, there is no "rename tag field" action type.

Kind regards,

Thanks, Florian. What is the expected behavior of a Format value action on a flac file when there are multiple fields with the same name? For example:

COMPOSER=John Lennon
COMPOSER=Paul McCartney

Action type: Format value
Formatstring: %composer%

Unfortunately, these actions do not support handling of multiple fields with the same name at the moment.

Kind regards,
