Dynamically create child_process args.

I would like one of my argument values to be dynamically created right before the child_process is spawned. Specifically my use case is to pass a a unique port number to each child_process `--inspect=AVAILABLE_PORT`.

I have been reviewing the src, and it looks as though this isn't possible. It looks like the args are hard coded in a cached settings.json file... Is this correct? Do you see any possible path forward to support the requested functionality?
