Customize registration process on buddypress

Membership Signup using a membership plugin [login to view URL] I'm using buddypress install for this project - I have two member types member 1 and member 2 Member 2 Signup form has 9 user types pr categories. Each type has a signup form however a user can Signup for multiple categories therefore the form must merge/ consolidate all relevant forms Ex. An artist can be a painter or sketch artist. Instead of a user signing up for both categories, both Signup forms are merged into one ( deleted the questions that are the same). Attached is the work flow of the signup process
