When libraries are ordering shelf-ready books, most of these records from the vendor include a barcode. The system preference marcitemfieldstoorder, does not accept a barcode to be included in this system preference, so the library can not save the barcode of the item that they are receiving. Currently, there are a lot of item level fields that can be used such as a non-public note, public note, URI, call number, etc.
This would be an amazing enhancement.
