Scheduled motion detection not just alerts

Why can’t we shcedule when to turn on and off motion detection and not just alerts I have indoor cams I would like on at night but not recording all the time also with motion sensors why can’t we have mode settings for alerts turn on and off alerts when leaving I have no need to hear alerts for motion detectors when home but I would like them when I am away and hate that to do that I have to shuffle through settings and then again when home
