Sort by artist name

Good day. I am searching the possibility to do with Mp3Tag this thing.

Format used : Flac (Vorbis comments)

To inverse the first name and last name

For example : instead of Bob Marley, I would like to have Marley Bob.

My idea is to use the tag ARTISTSORT for this.

How to do this?

With an action?

Many thanks in advance for your usual help
Regards

I think ARTISTSORT will not do it. You will need an Action using $regexp to change ARTIST. But this is tricky, and not for those unfamiliar with regexp and the issues of variation in the data format.

And then and Action to update ARTISTSORT accordingly.
