Deduct MLA parent commission from affiliate commission

Just mandatory, imagine if parent comissioner shares his code into a Coupon Codes website, then make 10 tiers. As of today, you must think really well how many tiers you want to add, otherwise it will make your business to get losses (100€ product, parent=25%, tier1=20%, tier2=15% ... tier10=5%, total payout 200€). What's more, due this fact, the MLA should have a limit of 5 tiers or 75% total.
