"File Types" - Identification

Currently RB uses the Title or Artist to identify the "File Type"

Would it be possible to have an option - tick box to enable - to use the Genre field?

Using the "title" field becomes a pain at Christmas 

We plan another thing: an addition tag field (like the ones used to store Playcount, BPM etc) to specify file type. This will allow to set file type and preserve existing tag fields. Modifying Artist, Title or Genre is not good in some cases...
