Is there a way to include custom theme colors in an add-in?

I want my macro to change the user's theme colors. When I try recording a macro and manually changing the theme colors, the code comes out just loading the ThemeColorScheme I just created (i.e. it can't really record my actions). So what I need is some way to place a custom ThemeColorScheme (xml file) on each user's hard drive through my add-in. Is such a thing possible?


Thanks
