Question on combining multiple orders, sending to ShipStation, and receiving tracking number?

When we have multiple orders ship to the same address, and we combine all orders to ship in ShipStation. Why the order that we choose to combine gets the order status and Tracking number updated but the other orders do not?
When you combine multiple order together in ShipStation, it will not generate record for each item or each order, it will only create a record for one surviving order once they are combined and once that is done, the status change and the tracking number will only update for Pressero order that is associated with this surviving order in ShipStation. Currently it is not possible to get the status and tracking number updated for all the order, if the orders are combined in ShipStation and this is a limitation of ShipStation and not of Pressero.
