I was wondering if there is a way to hide our integrated calendars from our co-workers. My team has Zoho booking and to properly schedule we integrate our master calendar (google calendar) with the booking app. But for some of us, both our personal and business schedule is on that integrated calendar.  We don't want everyone to see everything we have that is non-booking related. 

Is there a way for it just shows the time as busy but hides the details?
