commission question

I’ve been using a great membership system for some time and only recently found out that it does not allow me to pay my members for referrals the way I want to. I need to know if your system allows for my needs. Basically, in addition to paying members a commission on sales of various products, I want to pay them commission for referrals based on their own member level. For instance, say I have 3 levels; 1, 2, and 3 and I want to pay members on each level 25%, 50% and 75% respectively for referrals of a new paid member. Does your system allow for those capabililties?
