Receipt not on PO 8.03.403

We have a misc receipt line on a packing slip. It is an item that
came that we did not order. We may or may not keep it. When we get
the Invoice & then do receipt lines, it pull all items except Misc
lines. Epicor confirmed that it is as designed. Anyone have a work
around. I know we can do a misc invoice line, I am not sure how
accounting feels about doing that.
