Add additional Result Mapping options for Z39.50
It would be nice if there were one or two more fields where data grabbed via Z39.50 could be imported into ILLiad. In particular, "Item Num" would be an ideal place to hold a barcode, rather than having to concatenate it to a different value (as described here: https://support.atlas-sys.com/hc/en-us/community/posts/360006750353-Finding-Importing-the-Barcode-Field).

I strongly second the need to be able to pull the barcode into the ItemNumber field.
It would also be very useful to be able to pull in OCLC# and/or ISXN; we've had a few recent cases where an item was originally going to be filled through Doc Del but the item wasn't on the shelf. The standard numbers are visible in our marc data via Z39.50, but right now have to be manually copied over before we can send the request out to Rapid or OCLC.
