Add GTIN datafield(s) (aka SKU / EAN / UPC codes) to AT sync and (quick) search results

We would like GTIN-codes, when available in the Marketplace (datasets from distributors) to be fetched into the productcatalog besides the Manufacturer Part Number (MPN) and make it apear in the search results. Also, make it sync towards Autotask. Probably on the SKU-field of AT. Even when not available in the Marketplace data, it would be more convenient to add in Salesbuildr and sync from there into AT.
Why?
-We would not have to label products with a scannable barcode if its not (in a searchable format) on the product.
-Only few manufacturers have a barcode with MPN, but practically all have UPC or EAN (GTIN). Also are these codes more recognizable when handling the product.
-MPN's can be hard to remember when you have to type it by hand to specify the exact version of a product.
-In handling products we already use 2D/3D/QR/barcode-scanners to register the individual serial-, IMEI-, IPEI or MAC-data.
I'm aware of the troubles that 1 MPN can have multiple GTIN's. See comments.
