I have in the past stored function object(s) in flow/global but that means mostly using function nodes to access them.

No Biggie but not exactly the "node-red way" (imo).

You could of course make a multifunctional subflow and use properties of msg for parameters and `msg.topic` as the function name.  
Just be sure to use the self documenting features of the subnode to remind you how it works.
