Restrict view access of a (Maniphest) Task field to only a specific group of users?


For example, I have an Approver select (dropdown) field that is part of the form when I create a new Task. I want only a specific group of people to be able to see this Approver field when someone creates a new Task or edits the Task. Is there any way to accomplish this?


Anyone have an idea about how to do this?
