mhm... yes you have to create two templates.
I warn you, this will be hard to do.
first of all, copy the folder:
Then you have to create new tokens that will be usefull for your review template. A token is just a "shortcut" for a long microdata information.
Then you have to put these token inside your new template (removing the old ones).
Lastly, set the new template to be used inside the category.
As I said, it's not so easy, since you have to study and understand Schema.org dictionary, writing up a full markup for your new template.
