Allow server owner to set Home Directory of Email users

Virtualmin Theme version: 6.6
Virtualmin version: 3.65
Operating system: Ubuntu Linux 8.04.1
As root I can set the Home directory of a Mail user in the "Quota and home directory settings" section.

The server owner itself does not see the "Home directory" setting so he is not able to edit it by itself.

Also I don't find a setting in "Edit Owner Limits" which may prevent the server owner to edit the Home directory.

Is there any other way to allow setting the Home directory?
