Currently battling with multiple albums, which got their tags from CDDB in way where featuring artist is in tittle field.
For example:
TITLE = Blue Sky Action (Radio Edit) (feat. Alex Vargas)
ARTIST = Above Beyond
How to create an action or action group, to achieve result as:
TITLE = Blue Sky Action (Radio Edit)
ARTIST = Above Beyond feat. Alex Vargas
The forum covers many threads about this theme ... for example look there ...

Thank you for some reason, I searched the forum, but found nothing.
Only problem is that, method in that link removes everything inside brackets from TITLE field, will work troyght that thread and see, what I can come up with. 
Thank you, this works: Move "Featuring" from Artist to Title
