As an admin, I should be able to designate a folders zone (not restricted by the user).
In a closed environment where you have a single user designated as the owner, you are currently unable to utilize multiline tenancy. In an instance where UK HR Files need to have a zone of UK and US HR Files need to be in the US zone, I would need to create a separate service account to own each set of files.
Ideally you would be able to designate anything containing PII/PIA/IP to a root folder with a designated zone based on data storage compliance. Allowing multiple users to access without worrying about the need for unnecessary service accounts which is typically a no-go.
