Move ft artist to title

Hi!
I need an action to move ft. artist to title when the separator is \\ (no spaces)
Example:

From: Robin Schulz\\Rhys - Like You Mean It

To: Robin Schulz - Like You Mean It (feat. Rhys)

Thanks.

You could have a look at the 4 links in this thread:
/t/16236/1

The Separator \\ indicates a multi-value field so that apparently you have an artist in a title field.
jOin the fields first (there is an action)
then move the artist to the artist field.

Thanks.. :smiley:
