Report Purchase Price in an Item Receipt Search

I have a transaction search that reports Landed Cost data for Item Receipts (so, Type = Item Receipt).

We also need to report the purchase price (rate) for the line item so that we can accurately compute profitability.
I understand from NetSuite Support that when using Created From fields..., you can only access Main Line data.

Does anyone have any clever ideas for getting the (line item) Rate data from a PO when doing an Item Receipt report?

Thanks in advance!

EDIT: I've also tried the reverse of this search, a PO search where I report on the Item Receipt (Applying Transaction) fields. However, what I found was that the Account data was incomplete, I was not able to see all of the Landed Cost related accounts like I would if I did an Item Receipt based search.
