[support] Auto Assign Role + Content Profile

Hi, I'm trying to use Auto Assign Role and Content Profile modules on the registration form. I have 3 roles, A B and C (other than authenticated and anonymous) While using these 2 modules I get all the fields on a single page, while I need some compulsory fields for some roles and some other for other roles what I'm trying to get is something like this: http://www.preventgbvafrica.org/user/register with a page per role or something that let me do something like that with 3 different forms, I'm open to ideas.. thanks
