Paid Membership Pro Fix Needed - Wordpress

We have a couple of issues with paid membership pro we need resolved. 1. Discount Codes with Sponsored seats. We are using the sponsored seats addons and currently the discount code feature of pmpro doesnt play nice with it. Say a user purchases 5 seats at $50 dollars each – then PMPro charges $250 – all good there. If I create a discount code though the price(no matter number of seats purchased) becomes the price of the discount code – so not per seat. – not what i need:) I am looking for a way to apply the discount code as a percentage off, as I am using tiered sponsored levels also – so even if the discount code price were fixed and applied to multiple seats it still doesnt work). Example Scenario 1 I create discount code offering $35 membership price User buys 5 seats – price is still $35! Scenario 2 (which doesnt work but even if it did) 1-10 seats = $50 11-20 seats = $30 etc. Discount code offering $35 per seat would fail at 11-20 seats. On checkout also the number of sponsored seats disappears also. 2. Show discount amount on checkout I have customised the checkout page and would like to show the discounted amount in the checkout area.
