Middle click on tray icon to set specific brightness level

[Asteski]

Sometimes when I wake up my pc/laptop, it stays at the level which I've set before putting either to sleep and scrolling through to set 100% brightness can be slightly irritating. I know I can assign a hotkey to do that, but having an option to do that with middle-click on a tray icon would be nice to have, or maybe even add middle-click as available hotkey, so I can assign different actions as well.
