Hi there,
Thank you for using Paid Memberships Pro.
We don’t have a good solution for this, and it would require a fair amount of custom development to achieve.
You may be able to use a different plugin/method for initial registration – or keep it to the default WordPress registration. You may disable the register redirect for PMPro by adding the following line of code to your site – https://gist.github.com/strangerstudios/98a7d58a81b5becd5d0f
Once the user is logged-in and registered you may redirect the user to the level select page to choose a level they want to purchase and handle it from there.
I hope this helps get you started.
