How to add “supports” parameter for a Custom Post Type?

by

Is there a way to add support for a custom feature for a custom post type, after it has been created?

I know how to create a custom post type using register_post_type(), and how to use the supports parameter to specify what the CPT should support;

'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt' ,'headway-seo')

But for the situations when the CPT is being registered by a plugin or theme, is there a way to ‘inject’ support elements (manipulate the support array) of the CPT after it has been registered, using a WP hook/filter?

Yes, there’s a function called add_post_type_support

Hook into init — late, after the post types have been created — and add support.

Adding support for excerpts to pages for instance:

<?php
add_action('init', 'wpse70000_add_excerpt', 100);
function wpse70000_add_excerpt()
{
    add_post_type_support('page', 'excerpt');
}
