New Event attendance category

When adding an event, under attendance we can choose either private or public. I would like to add an additional category "Public/No Funeral Home" for those events the family is having on their own without funeral home staff assisting. This event would then need a different background color when it's merged to the calendar so when looking at the calendar staff members can see that there is an event but we are not going to it. We have multiple events like this every week, especially through our direct cremation branch.
