PO Line Description in GI

I have some generic stock/non stock items set up for certain purchases.  The buyer changes the description based on what it is.  The correct description shows up in the PO once it is saved, but I cannot find this field in the POLine table.  I can add POLine.InventoryID_Description but this pulls the description from the stock item, not the PO Line.  How do I add the actual PO lin description to a GI?

This GI below uses POLine.InventoryID_Description, but I want it to show the actual PO Line description above.
