[xmonad] Selecting xinerama screen with mouse-follow

Hello, I'm running xmonad on a two screen xinerama setup. To start a new application (for example, xterm) on an empty screen, I need to select this screen with keyboard commands first, then press the keys combo for starting the terminal. If the target screen has one or more windows already, it is sufficient to select a window on this screen by moving the mouse, so the new application will start on that screen. Is there a way to select an empty screen by method of 'focus my mouse' so new applications will open on the screen where the mouse is, even if the screen is empty so the mouse will not focus any windows already there ?
