#How do you make configuration/global variables in Node-RED that are configured once?

I have a handful of IKEA buttons where I'm using their ID to identify which button is pressed. But this isn't nice to update if I need to change things. Is there a way to make a global configuration variable where I can configure it and then just reference the variable/configuration in my nodes?

Alternatively, are there other better solutions?

I show you examples using the Change Node and the Function Node; these are both very useful nodes.
