Field MATCHES field

I want to filter singles that do not have the same TITLE and ALBUM value.

Like this: TRACK HAS 1/1 AND NOT TITLE MATCHES ALBUM

The only problem is that ALBUM is taken as a string. Is there a way to refer to it as a field?

This is accordig to documentation.

To filter for the result of a comparison between fields, try:
"$if($eql(%artist%,%album%),1,0)" IS 1
