Is there a way to extend Unity's window placement shortcuts?

In Unity there is the way of using Ctrl+Super+(left|right) to extend the current window eighter on left or right side.

Is there any way to extend this so you can place it in top_left an bottom_left ?

Window Placement

If you cycle through the same key Unity will cycle through different placement widths, so experiment by hitting the numkey multiple times, for example Ctrl-Alt-numpad 5 5 5:

• Ctrl-Alt-Numpad 7 - Place window in top left corner of screen.
• Ctrl-Alt-Numpad 8 - Place window in top half of screen.
• Ctrl-Alt-Numpad 9 - Place window in top right corner of screen.
• Ctrl-Alt-Numpad 5 - Center/Maximize the window in the middle of the screen. In 12.04 this toggles between maximize and restore state
• Ctrl-Alt-Numpad 1 - Place window in the bottom left corner of the screen.
• Ctrl-Alt-Numpad 2 - Place window in the bottom half of the screen.
• Ctrl-Alt-Numpad 3 - Place window in the bottom right corner of the screen.
• Ctrl-Alt-Numpad 0 - Minimize the current window (Ubuntu 12.04.1).
