I can't find any way to do this, I hope some advanced users could help me...
Let's talk with examples.
My original file tags: TITLE: BWV 123 COMPOSER: Bach (Johann Sebastian)
I want to add the "Composer" field inside the "Title" field, BUT keeping only the characters until the left parenthesis, putting a separation mark (like "/" for example).
So, the file title would become: TITLE: Bach/BWV 123
I tried the "FORMAT" action, but I can't find the right regular expression and scripting functions to do that...
Ehm... Just to make things more complex: is it possible to include in the TITLE tag not only the composer's surname ("Bach") but also his initials that are inside parenthesis?
