TCP output node - dynamically change HOST Address

#1

We have the Host/IP address hardcoded in as "192.168.1.74" and that works ok.
However, we are looking to dynamically change the HOST/IP address via user Input.
For example, we will allow User to enter tenter in the IP address and that will "SET" the HOST IP Address of the TCP Output node. For example, user may want to talk to "192.168.x.x"...

I did not see any way to 'inject" the HOST/IP address into the TCP OUTPUT node using msg.payload or msg.url.
ANy ideas?
