Multiple Google Calendars?

[BostonMike]

Use Case:  I want to get Alexa to read ONLY my calendar events for me, and ONLY my wife's events when she asks.
i.e.
"Alexa, what's on Bob's Calendar?"   <Alexa answers with only Bob's calendar events from his calendar.>
"Alexa, what's on Mary's Calendar?"  <Alexa answers with only Mary's calendar events.>

Is this possible?   I have both Bob and Mary's google accounts linked and in a single Household.  But if I go to Calendar in the app and select Bob's calendar it will only read Bob's.  But if I select both Bob and Mary's calendars, it will combine them and read both.  Even switching accounts doesn't seem to help.  Is there a way to do this?
Thank you!
