Change Realflight flightaxis default port

I am running SITL simulations using arduplane and realflight(9.5s) with some custom models. I would like to change the default communication port used by flightaxis. I am easily able to change the default port(18083) in SIM_flightaxis.cpp and set an input via “simulator-port-in” . Is there a possibility of changing the port number in realflight?
