TCP client 'mapping'

hello!

I have a set-up in which I like route traffic from several TCP clients. Node-Red will be the 'server' or listener.

The clients B,C,D are sending their status every second. All the statusses should reach client A.

When client A sends a command it should reach clients B,C,D.

Currently I trying a solution in which I have two servers, but command I am sending (from clientA) is still being mirrored back to client A since the TCP node says "reply to all open connections" for some reason it does not stick to the msg._session which should define which node to reply to.

Is there way to 'route' the the traffic with the TCP node?

I made all the connections in 1 flow for testing like this:
