I'm not exactly too sure about this feature you are talking about but CookieRevised's reply to Individual contact notifications possible? might have the answer you are after (there are many other things very similar to what is talked about in that post that you will spot when following the steps).  I hope this has helped, if this is not what you were after can you please give us more information so we can be of service for you.
