Does PO Approval have the ability to compare unit price to purchase price?

We have a need to require approval of a component purchase when the PO Detail line exceeds the current ItemPurchase Price. We are going to move to a Purchase Price Level 2 so that the Price will be available in the F41061 file but should the purchasing clerk receive a quote that exceeds the current price on file it needs management approval. We are attempting to control the PPV on our manufacturing inventory.

I see that A9.2 has a revised Approval process that allows for selection of either PO Header or Detail files but all of the examples in the Knowledge Garden documents only mention total PO value or total line value control. I need a comparison between the PO Detail Unit Price (PDPRRC) and either the Supplier/Catalog Unit Price (CBPRRC) or the Cost Ledger file (COUNCS where COCSPO = "P") based on the Purchase Price Level of the item.
