decimal separator

New SW user here. I am trying to set up our company drawing templates. I have set the default for the inch drawing templates to show dimensions separated by a decimal point as per ANSI drafting standards. Additionally I need to set up our metric templates to have a comma separator as per ISO standards. The problem is when I change the default it is under the system options so it is driving both templates. How do I make them different? I would have thought by selecting ANSI standards in one template and ISO standards in the other that they would actually follow their respective standards.
