Affiliate for WooCommerce

i would love the ability to generate fix-cart coupons from the sum of commissions available, meaning if the sum of commissions is $100 and an ambassador wants to shop for $50, they can enter the desired amount per coupon and have it generated. (note: they themselves should be able to do that!)

currently, ambassadors need to tell me the amount per coupon they require, and i manually need to calculate the individual commissions to sum up the closest as possible to reach the desired amount. super tedious and not nice and easy UX!
