Formatting Artist Field

Hi, is it possible to batch change the artist field from "Artist 1, Artist 2, Artist 3" to "Artist 1, Artist 2 & Artist 3".

Try an action of the type "Replace with regular expression" for ARTIST
Search string: (.*), (.*)
Replace string: $1 & $2

That replaces the last comma with an ampersand

Worked a treat, thank you!
