SHIPSTATION - please add Split Shipments ability to integration

At current, using SHIPSTATION AS A SERVICE, can push shipping information from CORE to Shipstation, but it fails when the Sales Order requires more than 1 shipment.     If there is a Sales order has 2 packages to be shipped, it still enters Shipstation as Single Sales order with 1 shipment. 

Please add this FEATURE into the integration, together with the ability to pass Packaging Dimensions to the data flow.
