I released an update of this plugin that I believe can help you achieve your results. It has a new plugin parameter that lets you play common events every time a character changes its image file and that image filename contains specific text on it.
You can decide what kind of text will trigger the common event. So you can create a configuration that when the character filename has the text "car" on it, it will trigger a common event.
And on that common event, you can change the character's settings you want. Please take a look and let me know!
