Purchasing Parts Price History

I have observed than when we accept the pricing from different suppliers and we create a PO, the old pricing replaces the price entered in the Supplier Response process. This is taking our Purchasing department a long processing time. Our parts are "parts on the fly" and mostly steel material so the pricing varies every day even for pieces that have the same composition and dimensions.Modifying the price 2-3 times is just not efficient for our process.

Did anyone have an issue like this?
