Custom Post Type in Reading Settings?

Is there a way to add a custom post type to the “Reading Settings” (Settings -> Reading), that would allow me to assign a static page to display my new custom post type?

I’ve created a new custom post type that I called “store”, and created simple theming to display each item in single-store.php, or to display all the posts in page-store.php. It all works just nicely, yet I’d like to add “Store” to my navigation.
