I apologize if this has been asked before, but I was unable to find any reference in the available questions. Looking at the Permissions tab under a mailbox currently shows all of the roles options, i.e. Author, Contributor, Owner. Though under the calendar section it seems to be missing “AvailabilityOnly”, and “LimitedDetails”. If you set this on the back end it will display the current setting in the drop down menu. Though it will disappear if you change it to something else in the panel.

Is this something that can be added?
