Add attendees to a calendar appointment?

Hey all,

On my OG I had no problem making an appointment in my calendar and then selecting a contact as an attendee. When you do this, it would send the attendee a message to confirm their presence. It would also send a reminder at the time you selected when creating the appointment. I can't find this feature in the Bionic's calendar. Anyone figure it out? I hope they didn't leave this out.
