Multi level affiliate levels

I am new to using an affiliate plugin, the site is going to be a membership site with affiliate tracking so naturally using WPMU plugins that interface each other was a natural selection. But client wants to have two different payouts for different levels of affiliates. Same a normal level of 50% and then an Expert level of 60% is this possible?

I have been told that this is normal behavior with other affiliate programs, I just dont know the answer. Thanks.
