P-Series Manual Night Mde

Would like to have the ability to change your night and day mode via function key like we had in the S-Series. An enhancement on this would be to allow a single key to scroll through the modes. 

A step up even further would be to allow multiple call routes that can be controlled separately. 

Line Group 1 follows time and pattern A

Line Group 2 follows time and pattern B

Both would require a sperate key to manual change those modes.
