Pretty edge-case, but I have a bunch of content-types that I want to only show as one facet. In this case, I want the user to be able to perform a faceted-search, with the "Guided Search" showing:

Content Types:
-Users
-Pages
-Groups
-Events

However, I want the "Pages" facet to select all Blogs, Pages, Stories, Announcements, News, etc. Doesn't seem to be an option in faceted_search interface for something like this, what would be the easiest approach to this? (I'm OK with coding)
