iWork '09 Pages: Creating a Specific Type of Page?

This is really driving me nuts.

Pages has a hook called “captured page”, which is described in the dictionary as:

The template I’m working with has a handful of these “captured pages” or page types such as “Cover”, “Sidebar with Photos”, “Text Page”, etc. I’m simply trying to make a new page in the current document based on one of these types. I can easily see all of the available captured pages for the current doc with:

tell application "Pages"
	get every captured page of document 1
end tell

but I can’t figure out how to actually make any use of them. Just want to do something like make a new page using captured page “Cover”, for example but I’m stumped.

Thanks for any ideas!
