#16 Bind socketReader to a single port?

[Thomas Altfather Good]

Is there a way to force socketReader to SEND from a specific port? At the moment it is sending from one port, waiting briefly for an MLLP ACK then resending the message from another port. The net result is that the remote server replies but I never get the ACK because it is replying to the original port. Ideally I would like it to transmit / listen on one specific port. Can this be done? Thanks.
