80: Automated Calendaring

My workplace uses Office 365, and the scheduling assistant can only view the primary calendar. Instead of having multiple calendars, I’ve had to resort to using categories and color coding different event groups for easier recognition of them.

Any thoughts on how to make a particular category disappear from view? If I could toggle them on and off it would be similar to toggling calendars. I have Fantastical, and looked at the calendar sets, but did not see a way to select by category.
