Windows 7 Folder contents in Jump List

Question

I'd like to know if there's a possibility in Win7, to simply drag folder to the taskbar (which, afaik cannot be done in normal way) and display it's contents using jump list.
Example: You drag desktop folder to the taskbar, and jumplist, is it's contents.
I know about applications like JumpLaunch, but I do not want to manually modify anything in order to display folder contents.

Answer 1

I've read somewhere that even Microsoft staff confirmed it impossible. I can't find the source now though.
