Restrict a specific calendar event to being viewed by only certain user groups

[mhuckaby]

Hi,

I want to enter an event in my calendar and restrict that specific event (not the whole calendar) to being viewed by specific user groups that I give permission to. For example, Let say I have a calendar and I have 3 user groups and they are: Group1, Group2, and Group3. I want to enter a new event, but I only want to have Group 1 and 3 be able to view/edit the event. Then maybe I'll add another event, but this time I only want group 3 to view/edit it. How do I do this on an event level, instead of having to set up a calendar for each group?

Thanks!
