Link Categories to custom field in registration-form?

Hi!

I’m trying to create a register-form which allow users to check for their title.
Ex: if a drummer register for my site, I’d like him to just check the radiobutton that says “Drummer”, and then this information will show in his userprofile and in searches done by other logged in users.

I have tried other plugins, and in that prosess created categories for the job-titles I’d like to have in the radio button-list.

Is there a way for me to use these Categories in Pie Register?
