Since we're able to have multiple boxes / shipment and split shipment. It would be great if Shipstation has a way to record which items were actually packed in which box. Example: Product A in box 1, product B/C/D in box 2, product E in box 3, etc.
Then we would have multiple packing slip telling the customer what's inside each boxes.
Useful for our company and for the customer. The customer doesn't have to open a box to know what's inside. Our company has assurance that the order was packed correctly can protect ourselves if a customer claims part of the order was not received.
If we're allowed to ship multiple boxes through Shipstation, Shipstation needs to support packing slip for mutli box shipments.
