Is it possible to block a category from Upcoming Events?

I’m afraid it’s not currently possible to block a category from displaying events in the Upcoming Events calendar (though the events would only display for people who had permission to see the category, if that’s any help). I’m not sure how a Template of an event would work though? There is a ‘recurring’ option in the event itself if you had a regular weekly meeting, for instance. You can set it up to add a new one each week when the existing one has ended?
