Possible to sort multiple post types on the same page?

First of all, thank you for an amazing plugin; have been looking for something like this forever!

One question: I need to sort multiple post types on the same grid (posts, movies, pages). I tried to specify them during registration in an array, as follows, but no luck:

add_action('init', 'site_register_wp_grid_sorters');
function site_register_wp_grid_sorters()
{
    if (function_exists('wp_grid_sorter_register_sort_key')) {
        $args = array(
            'name' => 'Sort All Posts',
            'post_type' => array('post', 'page')
        );
        wp_grid_sorter_register_sort_key('sort_all_posts', $args);
    }
}

Is there any way this could be done? It would be perfection.

Many thanks in advance.
