how do i add a launchpad app folder to the dock

i have this folder in laucnpad with all my video editing apps ,instead of clicking on launchpad/folder name/app

i want to add that (folder name) to the dock , i google and all i saw was how to add the entire folder application to the dock and i don't want that
you know how in ios you can add folders with whatever apps you want and name

is there a tweak/hack/app to make that happen in mountain lion
