Hiding Activities in Mass amounts

I would really appreciate a way to hide our All Day activities from the calendar in mass. For ex. AD puzzles, AD walks, AD social circles. Some of our families want to know that their family member is out socializing, but know they aren't interested in the more scheduled activities. These activities allow us to take attendance, but are not necessary for our calendar. I just want a way that I don't need to go day by day, activity by activity to hide them.
