NTRP ratings on accounts

We offer NTRP computer rated classes and self rated classes. However in a patrons account I can only select one  NTRP.  If they are self-rated this still allows them to sign up for the computer rated class. Can you add more categories for NTRP 4.0 and NTRP 4.0S, NTRP 4.5 and NTRP 4.5S. This way self-rated players can enroll themselves in the self rated classes each session rather than having to submit a request and I approve them.

Thanks!
