Feature Request: Make 'role' lists available on database tab

Would it be possible to make the 'Role' lists used to autofill the 'Author and Performer', 'Production' and 'Musician' roles available for editing somewhere? A number of the other lists are available on the 'View -> Preferences' property page, Database property sheet.

For example, this would help me add certain musical insturments that show up a lot in rock music, but that Orange does not recognize. The Mellotron and Tambourine are two instruments off the top of my head that OrangeCD doesn't know.

Thanks.

I'll bump this request back up.
