[otrs] Group Selection on new Account Creation From

Hi, I have some groups created, to which belong some queues. When a customer accesses the customer account creation form, I want him to be able to select, via dropdown box, a specific type of group, and then have OTRS automatically make the correct CustomerUser<->Group assignment, according to that selection. I've been looking inside the code for this, but it's still not clear to me what the best approach would be for this. Any hints?
