How can I place calendars in multiple calendar groups?

I would like to use a group for each of my family members but reference some of the same calendars from multiple calendar groups. Here is an example:

Lets say I have a calendar for school, sport1, sport2, activity, family, and work

I would like the groups to look like this:

Me: family and work
Wife: activity and family
Son_1: school, sport1 and family
Son_2: school, sport2 and family

When a group is visible, that person can see the activities in which they participate. When several groups are visible, though, only single copies of shared events would appear and shared events would only have to be entered once.

Is there a way to do this or do I need to place this on the feedback page?
