Well said SCC.  For software of Shopify's caliber, it's absolutely mystifying how many things defy 'basic database architecture.'  Another example is the inability to 'Print Labels from PO.'  Instead you have to re-enter all items manually!  Was hope...

Thank you for sharing this clever work-around!  That said, I'm still hoping Shopify will add 'Print Labels from Purhcase Order' functionality directly on PO page.  This will allow quantities auto populate to exactly match that of PO

Agreed.  This issue needs to addressed asap.  Many new migrating customers will be baffled that this functionality doesn't exist.  'Print barcode labels from PO' - should be an easy update for software of this caliber.  Get on it Shopify!
