Allow contacts/attendees to Cancel & Reschedule events using Meetings

I use Acuity and many of our consulting clients use Acuity or Calendly. We CANNOT switch to Hubspot meetings until there is a cancel / reschedule feature added. This means that we have to write and maintain NUMEROUS zaps and workflows to do the same thing. PLEASE make them options, so I can disable cancel and enable reschedule. Also, we need the ability to add different appointment types and locations.
