Separate buddypress and store registration

Greetings, I have gridmarket multisite running and buddypress running off a subsite (so that I can have a seperate theme). I need to have serperate multisite store registration from the buddypress registration. For my multisite stores they are allowed more than one store and they need to register their store categories. Before buddypress the user would go to the store registration and fill out the site descriptions etc...Now they are hijacked to the buddy press site and not given the option to add a new store. How can I keep buddypress registration separate from my multisite store registration?
