Morning Team,

In addition to the standard message being passed between nodes I would like to pass a few additional parameters to a following function node.

I would like if possible to retain the original message if possible.

A message is by no means restricted to payload and topic.  
You can attach additional data in a change node or a function node:

```auto
msg.coreTemperature = 475
msg.output = {"volts": 400000, "amps": 800}

```
