Filename to Tag - Logic

Hi all, having some problems with my logic statement.

Music file name is:
Pitbull & Bon Jovi - Now Or Never (Intro Clean) 128.mp3

I am using filename to tag function: (code below on what I used)
%artist% - %title% (%title%) %dummy%

That gives me:
Pitbull & Bon Jovi - Now Or Never Intro Clean

Close, but I would like to keep the parathesis so it reads:
Pitbull & Bon Jovi - Now Or Never (Intro Clean)

Tried:
%artist% - %title% "("(%title%)")" %dummy%
But that didn't work.

Hello fcastro, my audio files are tagged like this, to have the names of the artists and the name of the album while keeping the data in parentheses (xxx)
%artist%-%album%

Result:
Artist-Album(2024)

To have a space between the Artist and the Title and keep the data in the parentheses, you can do this very simple programming

%artist% - %title%

Result
Artist - Title (Your Data)

The problem is: the space character is no unique separator.
So, with Convert>Filename-Tag you would get as close as

for TITLE, losing the closing parenthesis
with
%artist% - %title%) %dummy%
You could alternatively use an action of the type "Guess value"
Source string: $regexp(%_filename%,(.*) \d+,$1)
Target format string: %artist% - %title%
Or you stay with Convert>Filename-Tag and apply a filter afterwards to reduce the list of files to those that have an opening but no closing bracket with
%title% HAS "(" AND NOT %title% HAS ")"
and then execute Convert>Tag-Tag for TITLE
Format string: %title%)
