Redmine

I created a customer role without time tracking permissions. I was hoping this would also disable viewing of start date, due date, estimated time and % done fields when creating or viewing issues under that role.

Is it possible to achieve this ?

If my customers are creating , editing and viewing issues they have created these fields should be dictated by the role permissions.
