Motion Zone/Sensitivity Scheduling

It would be really useful if you could have a schedule button in the motion tab for different motion zones/sensitivities. For example, at night I get reflections in areas which triggers motion alerts, whereas normally in the daytime it wouldn't. If I could have a different motion zone/sensitivity preset for night time I could avoid these alerts. It could look just like the recording tab with the grid of squares for times and different motion zone presets as the colors.
