Price Break discounted amount not visible on the PO?

Summary:

The discounted amount from the price break defined on the BPA should be visible on the PO.

Content (required):

I have got a Blanket Purchase Agreement with a price break defined e.g. $100 item with 2% discount for 5 pieces.

When I create the purchase order with a quantity of 5, the line price is automatically updated to $80 as expected. However, there is no breakdown available on why it's 80. I imagine the supplier will want to see the discounted amount ($20) but there is no reference to the price break on the PO.

I understand there is a separate feature for enabling Discount Type, Amount and Reason on the PO line, but this is for manually applied discounts and not the automatic ones from the BPA.
