We often end up making purchase orders in printavo that include the goods/items for multiple invoices and when the boxes come in from alpha broder, its great to just look at their packing list and see the job names listed there in the PO so we can begin counting and sorting with that in mind. Maybe an additional field to add multiple invoice numbers or nicknames to a purchase order that can be analogous to the "special instructions" or "csr" field in the alpha packing slip (attached).

Hope this is helpful.

Thanks
