Single step gravity form and membership pro 2 member registration.

Hi, I have read threads on Gravity Form and Membership integration. I have implemented as instructed i.e Created registration form with Gravity form with user registration add-on, added code to auto login after registration and added redirection in Gravity Form to membership pro registration page.

It worked as expected. I registered as shopowner and I am directed membership registration page with 2 membership options i created (Shopowner & Shopper). However, this is a 2 step process.

So i would like to know if it is possible to cut that into a single step? Does Membership pro have url parameter I can use when i redirect from Gravity Form?
