Answer 2

To me this is screaming for a contentrule (really like them) and collective.contentrules.comingsoon claims to be able to do what you want, since of version 1.1 passing the index-parameter is possible.

And the latest release is quite fresh, which hints, it was used with newer Plone-versions.
