How do I rename saved sample banks?

How do you rename a saved sample bank in Cross DJ? Renaming the samples themselves is fairly intuitive, but I want to rename the sample bank to simplify selecting the correct bank on the fly. For example, instead of "1 - New Sample Bank" I would like it to say "G Minor Bass Lines" or "Tribal Conga Beats" or whatever.
Forgive me if this is a stupid question, but I've tried everything I can think of and I can't figure this out.
