Users with admin access can control and limit non-admin users' ability to update spec/selections and schedule templates.
To do so, go to Contacts >My Team and click "Edit" from the ellipse menu next to the desired builder user.
If you check the "Update Templates" permission then the user will be able to view, edit and create selections and schedule templates.
If you uncheck the "Update Templates" permission then the user will not be able to view or edit schedule templates. He or she will only be able to see the list of your existing schedule templates. They would be able to view your Spec/Selection templates but can not edit items in any way.
