Once you have set up a new schedule, you may add an additional schedule on the same device by following these steps:
Tap the "three vertical dots" icon to the right of your device's name. Or swipe from right to left on the device.
Tap the calendar icon on the slider then select the "+" button in the upper right hand corner.
Using the dial, set your desired time. (For iOS you can drag the time around the dial; for Android, you need to move each end of the dial.)
Tap the days of the week that you want the schedule applied to.
