Cancellation format

In these unfortunate days the show cancellations are more than ever a subject. 

I'd love some kind of feature to cancel a day and/or a single event without having to erase it. 

I don't want to erase the date/event since there's information I might need for future reference but I'd love it the removed from dashboard, and to be formatted in a way in the mobile app that it's still there but very clear that it's cancelled. 

Would also be great if it's removed from the statistics.
