Template option does not show in wordpress custom page

I'm creating a new tab that is the same as "page", but separated as the image.

TheproblemisthatIcreatedacustomtemplate,thatis,Icreatedmytheme,inthe"pages" tab the template option appears

Inthe"locations" tab I created, the template option does not appear, does anyone know how to put it?

Follow the code for the register.

function locations_register(){
    $labels = array(
        'name' => _x('Locations','post type general name'),
        'singular_name' => _x('Locations', 'post type singular name'),
        'add_new' => _x('Add new location', 'location'),
        'add_new_item' => __('Add new location'),
        'edit_item' => __('Edit location'),
        'new_item' => __('New location'),
        'view_item' => __('View location'),
        'search_items' => __('Search location'),
        'not_found' => __('Nothing Result'),
        'not_found_in_trash' => __('Nothing result on the bin'),
        'parent_item_colon' => ''
        );

    $args = array(
        'labels' => $labels,
        'public' => true,
        'publicly_queryable' => true,
        'show_ui' => true,
        'query_var' => true,
        'rewrite' => true,
        'has_archive' => false,
        'capability_type' => 'page',
        'hierarchical' => true,
        'menu_position' => 4,
        'taxonomies'=> array('features'),
        'supports' => array('title','thumbnail','editor','page-attributes') 
        );

    register_post_type('location', $args);      
}
