I have events manager plugin installed which uses custom post types for its events. I want to extend the events by adding some custom fields to them (like Twitter hashtag). The problem is that when I go into CustomPress, I do not see events in there. I see page, post, attachment, etc and all other custom post types I created within CustomPress. How do I get custom post types that were not created by CustomPress but form another plugin? Custom post types reside in the core WordPress, so shouldn't all custom post types show up whether they were created in CustomPress or not?
