Unfold pinned folders?

[Sethos]

Hey,

One thing I really, really want to be able to do is unfold folders you've pinned to display contents, exactly like it does when you press "All Programs"

Like here, press the Windows Accessories, you'll get the content;

However, if you pin a folder to the start menu, it'll just open it in a new explorer window.

Is it possible for folders to have that functionality when pinned to the front? or create something that has that functionality?

Thanks
