Not a Tagman Kind Of Guy

Tried out a software called "Tagman" as a potential music manager to replace Windows Media Player. I got some files imported into the tool, which allows 500 music files in its 'test' version. I went to the window in the software to set up rename rules and was greeted with a drop-down list of values, as shown below:

Unfortunately, as I explain in the text on the screenshot, Tagman doesn't allow the files to be named what I want them to be named.

Uninstalling it now.

No Answer = Impossible

I had the same goal as this forum thread - How to add mp3 tags to an explorer's window - from August 2014. See how the Composer column is displayed but is not available in the lower part? I want the "Genre" field to be the same value as the "Composer" field. The "Composer" field is how I store the spindle on which the CD is stored. I can use Windows Media Player to append the "Genre" value to the file name, but not the value in the "Composer" field. By having files named with this naming convention -   01_SongTitle_ArtistName_AlbumName_Genre.mp3 - I would be able to know exactly where the file should be stored. It would be very beneficial as the cleanup of my audio files continues.
