Marquee functionality to assign specific monitor

It would be great if we could assigned the marquee screen to a specific device instead of just the number that is randomly assigned by windows. The current implementation is not very reliable if e.g. a third display is used, because bigbox only supports two displays. Using the third screen plugin does also not solve this, because things like screensaver mode do not work properly i.e. the plugin seems to not register the changes of screensaver mode properly.
