How to split the popup "Buffer Menu" by major mode?‏

[Pony]

When press click the left button with ctrl key pressed (<C-down-
mouse-1>), emacs will run the command "mouse-buffer-menu".

If I open a lot of buffers in different modes, the popup menu will
generate several submenus as "Buffers 1", "Buffers 2", "Buffers 3" and
so on.

Is there a way to make the popup menu split according to buffers'
major modes? For example, "C++", "Java", "Org-mode"?

Thanks in advance!
