Well, you don't have to worry too much about the format. Mostly I just
wrote a plugin which does what you want. The plugin uses some advanced
tricks to handle an arbitrary list of options, and pass them on to
another command. All it really does is override a single parameter to
make sure it is set in a certain way.

The above is a generic template that you can use for any function you
want to overload, and set a default value.
