How can I create CASCADING folders under start menu (on top of all of MS's stuff, not under Programs etc). Something like Programs or Favorites folder?

What I need to do now is to “ADD” a folder to the “Start Menu” (not replacing MS menu, just adding on top with CSIDL_START_MENU pidl) and
optionally show it as a cascading folder (like Programs).

I posted this a week ago without any luck. Someone please help.
