CustomPress Compatibility with Genesis 2.0 CPT Taxonomy Support

I'm using the Genesis Framework and CustomPress on my site. Apparently there is special custom post type support in Genesis 2.0 that would allow me to get archive pages, etc., without having to add separate template files (cf. http://www.carriedils.com/genesis-2-0-archive-settings-custom-post-types/), but the register_post_type() function has to supply the "genesis-cpt-archives-settings" value in the "supports" key.

Is there a way that I can add this value to the "supports" key in this function?
