How to issue Mavproxy commands from within Mission Planner

I’m new to SITL and I’m trying to get SITL working with Realflight. I’ve been able to get it to work using the Simulation tab in MP with flightaxis as the model, but I don’t know if there is a mavproxy console from within MP that I can use to issue commands. In the past, I was able to use --console --map to get a console, but using MP it doesn’t appear to work the same. I’ve tried starting mavproxy on its own and connecting to but couldn’t get it to work. Any suggestions?

There is no MavProxy in Mission Planner SITL.

I was able to get this working by forwarding the mavlink stream using the advanced mission planner features as outlined here:
Then I started mavproxy from the command line and was able to use it to issue commands.
There may be a better way to do this, but this seems to work.
