Discount and Markup

I have some contracts where the manufacturer is offering a discount to the distributor. The distributor is then marking up our agreed percentage based on that discounted price. Is there anyway I can load the base price as the undiscounted price (so buyers can verify that pricing from our purchasing group) and then calculate the discount and the markup? I have noticed that PO25.3 only does one or the other. I did notice that in PO25.4 has a rebate option, however it doesn't seem to make the necessary change, I assume it's because the markup occurs before the discount and not vice versa. Any assistance would be amazing!!
