Problem: I would like to be able to reveal intermediary post types in the main wp-admin menu, and allow them to be queried in Views. The intermediary post types are currently hidden, because I set them up as hidden when I created the Relationship.
Solution: Edit the intermediary post type and mark the post type status "Published" to expose it to wp-admin and Views queries. Change the post type status back to "Draft" to hide the post type again.
