Disable specific calendar events from appearing in Google Now?

Re: Disable specific calendar events from appearing in Google Now

This is exactly the problem I have. My co-workers have shared their calendars with each other (I am the administrator.) We all have "Make changes.." permission, but don't use it. Google Now notifies me when another person has an appointment. I don't need to know when it's time to leave for Pete's doctor appointment! Can I deselect certain calendars from Google Now? As admin, am I stuck with seeing everyone's calendar as if it is my own?
