Customizable Categories: A wonderful feature to add...

Hi, i've been using RB for a while now, and it is an amazing program, compliments to the Pioneer Team!

One feature I would love on RB would be customizable categories, which would mean that I can add a category (like Artist, Track, Album, Remixer ecc) but can change the name of the category heading to whatever I want. This would make it easier to make personal distinctions between tracks and add certain categories that may not be common to everybody.

Cheers
