Ability to Override Blank Product Prices & Add Markup

Sometimes blank supplier products are not correct. We can override the product prices, but we have to add the supplier cost with the markup to create the final price. We really need the ability to set a price and then the % markup gets added to it. 

Within the "Supplier & Purchasing" section we can set the SKU unit prices, but it is only for raising a PO. We really need the ability to use the manually set SKU prices to become the Supplier Base Price so the Markup % can properly calculate the final price automatically.
