Multiple Terms for Items on a Purchase Order

I am looking for a way to assign different terms to individual line items on a purchase order before the voucher match.

I understand that I can override the terms at voucher match but I am looking for functionality similar to Sales Order preferences override payment terms.

We are on 9.0

In our situation we have Freight as a separate line item on a PO but we have different payment terms that the actual items we are purchasing.

We don't want to split into separate POs

Has anyone had a similar need and found a workaround?
