Insurance costs should feedback as charge to OMS

Right now in the system when insurance is purchased through API call the insurance is purchased, but the cost information for the insurance is not sent back through ShipEdge. This means that if we want to recover insurance costs we have to audit insurance costs through shipping API, rematch up with orders ,then add as an additional charge to our client's transaction logs. It would make sense that when insurance is purchased, cost information is relayed back to system in real time and added as a charge to our client's invoice, and as a line item as a cost of the shipment.
