The majority of our orders are multi-package shipments. This functionality in ShipStation is lacking. There is an option to add our own Custom packages under Settings however that does not work when creating multiple packages. Please add a drop down in the multi-package screen where the size, weight and insurance amount is located so when we select the custom package the dimensions and weight is automatically filled for each package. This will help with linking up the items/quantity that has shipped under that package tracking. We need to know what item & qty corresponds to each tracking/package. All this data needs to be available in API to send to NetSuite.
The current solution of having to split orders is costly, or creating sets, does not work for us.
