Post types customization

Hello,

I use custom post types (and CPT UI), Can you please tell me how to create list of custom post types?

I suggest 2 ways to handle that:

1. Create a new wordpress filters for settings. Something like: apply_filters( 'ultimate_post_list_' . $section_key, $section_values );
2. Add specific post types support. Something like: add_post_type_support( 'post', 'ultimate_post_list' ); then getting the list of post type filtered with this support.

WDYT?
