Splitting the planned shipment according to cost center

We have a planning scenarios where multiple orders are consolidated planned into one shipment(multi pickup and multi drop). The planned shipment has to be shared to the external system. Each order associated with a specific cost center must be sent using a separate planned shipment transmission, eventhough all the orders are planned into one shipment. This includes splitting not only the orders but also the shipment stops and ship units based on the cost center.

Can you please provide your suggestion on the above, if you have come across similar requirement.
