I think we could ask Andrei, what I've found out could solve our different needs in one similar way. ;D Meaning:

As we all have different "needs and ways" of using this (great) database, it is my opinion that some of it's pre-defined fields should have customizable names, specially in the Credits feature (in disc and track properties), for we all do not use them for the same purposes.

It is very likelly that version 5.3 should bring some 'forwards' on that direction. Let's wait...
