Populate Vartable from Environment Variables

[ChZeman]

I'm using Node-RED to monitor around 50 pieces of equipment, each with a unique control system and a variety of processors. I'm using the same flow in Node-RED for all of the machines for ease of deployment and updates. The flow is designed to act accordingly to environment variables. It doesn't appear, however, that the vartable for node-red-contrib-cip-ethernet-ip (and I imagine node-red-contrib-pccc and node-red-contrib-s7) can be populated using environment variables. Deployment and maintenance would be so much easier if I could programmatically add the tags and addresses.
