You don’t. they’re suppressed.
What I did, is create an analogous Simulated Presence Sensor for both me and my wife, then used WebCoRE to set those based on the status of the built-in presence sensors. Bonus side effect, I can apply intervening filter logic such as - never set sensor X ‘away’ if a certain calendar item is present in [this Google Calendar] (I’m using GCal Search [UPDATED 3/27/18] GCal Search for that functionality BTW)
