I have S2Member Pro and IDev affiliate - Can I Automatically make a subscriber an affiliate?

I am putting together a membership site for a huge project and want to make S2member automatically create an affiliate ID when someone subscribes.

Is this possible?

I have S2member pro and iDevaffiliate black.

Not a web developer, just trying to help my son get his site up for his launch at the end of October.

Thanks for your help!
