Recurring payments to affiliates

Hello all,
Just wondering if there is an option in the Affiliates plugin to enable recurring payments.
We are building a multisite/prosite install and for every site that registers, the affiliate get paid a percentage of the subscription each month until the account is closed.
I can see that with the prosites addon you can set the percentage the affiliate receives, but can see if we can make it on going.
Thanks,
D
