Restricting access to saved documents within a worksheet
Is there a way (sorry if this is obvious) to restrict who can see documents saved in a task plan? I believe I can restrict based on an access level (Viewer, admin, User, etc..) But can I restrict more granularly? From an info security perspective, I am being asked to restrict who can view certain docs saved to a plan even if they have the same access rights (Viewer, admin, User, etc..). For example, Bob who is a user can see the contract saved but John who is also a user cannot.
