How to arm when at home while sleeping?

If I've set it to "Home" but it's during the day time, we don't want to have to disarm every time we're opening the front door for example (unloading groceries, spouse leaving for errands, etc.)
However we do might want to have an alarm set if it's 2AM and everybody's sleeping.
Is there a way to configure that?
We have a base station, entry sensors and a motion sensor.
