how to register as user before as vendor?

hi

i created a menu for the vendor edition. is it possible for the user to register as member first?

at the moment when vendor edition is clicked both basic registration and vendor registration appear on the same page. I just want to show the basic joomla registration first, After he has registered he may now apply as vendor.

thanks
