Yeah, I came here looking for answers to the same problem. My GF and I share the same Amazon account. We both place items into the shopping cart and when we check out, multiple TBA shipping numbers and delivery dates get generated based on where the items are being shipped from, Amazon warehouse or 3rd party sellers. Yet the Deliveries app lumps them all into one delivery line with different tabs, #1 motor oil, #2 shampoo, #3 motorcycle exhaust pipe, #4 fingernail polish, etc. I wish I knew how to make TBAdelivery numbers their own line.
