How re-arrange order while inserting tag from field in filename?

Hi!

I am trying to change with a batch action the name of my files in a playlist named to insert the Artist before the title name following this pattern and logic.

From:
02. You & Me (Rivo Extended Mix)
where 02 is the playlist track number but NOT the track number in the %track% field (in this field it refers to number in the album it pertains originally and would like to keep it that way if possible)

To:
02. Disclosure - You & Me (Rivo Extended Mix)
where Disclosure is inserted and populated in the %ARTIST% field without changing the track# or title from the tags

To achieve this, I have created an action Replace With Regular Expression like this:
Field: _FILENAME
Regular expression: (^\d{2}\.) (.+)
Replace matches with: $1 %ARTIST% - $2

But it doesn't insert the artist in the filename (for example Disclosure), instead I end up with:
02. %ARTIST% - You & Me (Rivo Extended Mix)

I have also tried to do it with the filename to filename converter like:
Old filename pattern: %1. %2
New filename pattern: $num(%1,2). %ARTIST% %2
But it doesn't work either...

Could you please let me know what I am doing wrong or how to achieve my expected result?

Thanks in advance

I think that this is a good approach but you have to use a function that allows a format string to get the contents of %artist% as string.
So try either an action of the type "Format value" or Convert>Tag-Tag for _FILENAME
Format string: $regexp(%_filename%,(^\d{2}\.) (.+),$1 %ARTIST% - $2)

It works perfectly. And now I understand what I was doing wrong. Thank you Ohrenkino, much appreciate your help and fast response!
