Option to verify that given command is supported by grc rules

[z0rc]

I'm looking for way to automatically alias all commands that supported by given grc configuration. Right now my approach is dumb, it verifies if there is conf.${command} file present and aliases this command. But as grc.conf defines regexp that could match multiple commands, my approach is suboptimal.

What I'd like to have is an option to check, if given command is supported by current grc configuration.
