I like the events module in EasySocial, but I need a way to organize attendees by shifts for teamwork.

Example: A volunteer event is created with three shifts (9 A.M., 1 P.M., and 5 P.M.), and ten people RSVP. They need to select which shift they can work on.

Is there a way to do this in ES, or is there some team collaboration extension that I can add, so that EasySocial users can sign up for an event and indicate when they can work certain shifts?

Thanks.
