Is it possible to queue up multiple message to go to the same device?

            No, you can only queue one message at a time for a particular endpoint. Each endpoint has its own queue that is independent of the others. The purpose of the queued message is to immediately send a message to a sleepy endpoint when it has waken up and reported back to the coordinator. There is a period of time defined by the Listen Window parameter that determines how long the endpoint will wait for a message before it goes back to sleep. The queue feature allows a message to be sent immediately after an endpoint reports in with a supervisory message which minimizes the necessary listen window and thus maximizes battery life.
