Allow spreadsheet import of Country of Origin codes from spreadsheet to update stock item records Merged

With Brexit having arrived we now need to add country of origin codes to our invoices for customs reasons. We have recently done bulk spreadsheet import updates of commodity codes and net weights using the stock item import spreadsheet functionality. Unfortunately, it doesn't seem possible to bulk update country of origin codes for stock items using the spreadsheet import function. This means we will have to manually add country of origin codes to individual stock items which will be a very time consuming process (We have thousands of stock items). Please make updating of country of origin code field a function of the stock item import spreadsheet.
