Ravi,

We just did exactly this sort of thing for a project I've been working on. I
don't remember all the details now as I'm not at home at the moment. But
IIRC it involved modifying Elements/ShowCustomField (note singular form) and
then doing some checks for particular CF types. I got the idea off the wiki,
so that would be a good place to start.
