Incomplete register post type options and rewrite rules

http://make.wordpress.org/plugins/2012/06/07/rewrite-endpoints-api/#comment-665 says the endpoint (ep) needs to be part of the register_post_type(). I don't see any 'endpoint' options when creating/editing a CPT from CustomPress. Also, the plugin is lacking some rewrite support. I'd like to see some functionality like http://wordpress.org/extend/plugins/custom-post-type-permalinks/ built in, but most importantly, the registering of the post type needs to have ALL the possible options.

Thank you.
