I'm probably answering my own question, I want to do a bulk upload of procurement data that I've received from Dell - now the key is that I want to match the spreadsheet which contains the Dell service tags (or in Snow's case, the Bios Serial No.) - do I need to have the computer name? As the computer name is the piece I don't have time for - I thought Snow would map the spreadsheet devices to the bios serial numbers but unfortunately not, it looks like it needs to map the upload to the machine name. Is there a way I can get around this at all?
The only other way would be an export of all computers (Dell) and then a vlookup to match the Bios serial no's?
