Drop Ship Purch Order Cost change - E1 9.2

Hi. Our company places SD/OD Orders months in advance i.e.; Orders entered in Oct to be delivered in Feb. This can create problems if the supplier changes the Cost, and because of the high volume of transactions, manually changing the ODs is a problem/challenge for our users.

1- Considering the high volume of transactions, what is the JDE's best way of dealing with this, Best Practice?

2- Any Batch process that can assist with this?

I am aware of the R42590 and R45620 and that they won't change Costs on ODs. We are not using Standard Cost, we use Weighted Average. We are an E1 9.2 shop.
