Moving a secondary artist from the ARTIST to TITLE tags

Support
1

i found some examples with regexp's for multiple artists separated by "FEAT." which seems to work well.
However, I was wondering how I could do the same with multiple artists separated by a comma.

For example:
Example ARTIST tag: "Madvillain, Viktor Vaughn"
Example TITLE tag: "Fancy Clown"

End result ARTIST tag: "Madvillain"
End result TITLE tag: "Fancy Clown feat. Viktor Vaughn"

Is there any way to have this happen? Also, if for example, there was a 3rd artist:
For example:
Example ARTIST tag: "Madvillain, Viktor Vaughn, 3rd Artist"
Example TITLE tag: "Fancy Clown"

End result ARTIST tag: "Madvillain"
End result TITLE tag: "Fancy Clown feat. Viktor Vaughn, 3rd Artist"

Is there a way to automate this process within the same script as well?

Thank you!

Try an action of the type "Guess value"
Source: $regexp(%artist%==%title%,'(.*?), (.*)==(.*)',$1==$3 feat. $2)
Target format string: %artist%==%title%
