Configuring Vim Plugin for Codemirror

It appears that the vim plugin for Codemirror allows for configuring the vim setup like one could with a .vimrc file. However, I see no built-in facility in the TW plugin for performing this configuration. Is there a way, perhaps, to have a dedicated tiddler that acts as a configuration file, allowing me to set options and change keybindings for the vim keymap? Is there a better way to configure it?
