Not sure what you mean - can you provide more details?

i typically default commander options to something in a config file. only in this case i want to pass in a config file. should i just use 2 commander instances?

If you want to allow a config file, that should be within your own code, not the commander core. We're investigating a plugin system in the future - this may fit in there.
