Use branded tracking without an order

I would like to suggest the ability to use the branded email without crating an order. We push our order shipment information to ShipStation using the API. Because there is no order in ShipStation we are unable to use the branded email notification.  right now we use a custom email notification, it's just not as clean as the branded tracking. I believe we push everything that is needed for the branded page including: tracking, order number, item sku etc.
