Owner identity of "collapsed" calendar events

[egon1024]

I'm using Dakboard to display an aggregate "family" calendar in a common room at the moment. Unsurprisingly, there are individual items on calendars that are on more than one person's calendar - the ability to collapse them is definitely very important. :)

The one thing I've noticed is that the person that a collapsed event is "assigned" to (by virtue of associated color) seems to be somewhat random. For example, one of my kids has a weekly event that is on his calendar, but my wife and I figure out who is giving him a ride so we are both on that event as well. But no matter in which order I pull in the calendars, the collapsed event appears to be getting assigned to my wife (ideally, it would be my kid who owned this particular event).

I'm wondering if something could be done that would allow one to :

1. Make the person it is assigned to more definitive/predictable
2. Make the person it is assigned to "controllable"
3. Somehow indicate that it is actually "owned" by all involved people (best option, IMHO)

Thanks for any consideration of this feature. :)
