Recurring affiliate payouts

Hi,

Is it possible to do the following using the affiliate/membership integration plugin:

1) Pay my affiliates a recurring monthly payout for each signup

2) Pay an upfront commission that is different to the recurring payout. e.g. affiliate gets $90 for a signup and $40 for each month that person remains a member.

If it isn't possible, I'd be really grateful for any suggestions for how I might go about adding that functionality.

Thanks
