How to speed up price entry in Purchase Orders?

When entering a Purchase Order I have to enter each items price. Is there a faster way to do this so that the price comes up from what is already entered in our product menu?

This half works. The PO system is awful. Sometimes it records supplier SKUS and prices when I create a PO, sometimes not. Also the PO total always shows including taxes and not prior to tax + Tax = total. Basic items that Shopify missed.
