Print package description on label
When there is a multi-package shipment, we write the package contents into the "Description" field for each package. It would be great if that field could be printed onto the label, just like [Sku #1] can.
A different option would be to restructure the package creation altogether so that you can assign the products and quantities to boxes. This would allow ShipStation to know what you are putting into each package and therefore print the package contents onto the label.
