Why is this marked "solved" when it does not solve the issue?

Many vendors, not just Amazon, charge by the shipped package but present the purchaser with a single invoice. Costco does it. UPS does it when creating shipments. This is and will continue to be a PITA until it becomes possible to combine multiple bank drafts that add up to a single bill.

Doesn't have to be automatic. I think we're all fine with manual matching in this situation.

So, ladies and gents, please reconsider adding this functionality.
