Paying commissions

Hello. I am new with this plugin and i am trying to understand how it works. I have understood how payments works but etc. if i have more than 1 unpaid commissions for the same affiliate (if i set the minimum is 45$) and the one by one commission cost 2$, when i create a payment by bank transfer i dont want to pay each 2$ for the same user, i want to unite commissions and pay total unpaid value. Is that possible and how?
