Ax2012 - Process outbound messages sequentially

Hi,

Assume I have two ports SalesLine and SalesLineUpdates, both with messages in the outbound message queue. 
Is there I way to control the order in which those messages are processed? I.E. I always want the SalesLine-message to be processed before the SalesLineUpdates.

I have found a way to control this for inbound messages with filenames and message-batches, but nothing similar for outbound messages.
