Is there a way to give access to certain statuses on Service Appointments to certain users?  For instance, I would like to block "Cancelled" from showing on the mobile app for FSL.  I do not want Field Workers to be able to change the status on a Service Appointment to "Cancelled" but would like the Dispatcher to have this ability.

Can we add additional fields to the gantt display in Field Service Lightning?  Right now, the only thing that shows is the Service Appointment Number.
