You can add template path in Allow Template properties of your site hierarchy root page
Click on Site hierarchy-> Click Properties -> Go to Advance tab-> Go to Template Setting Section-> Allowed Templates -> <Add path of the different folder which you wanna use>
Save and close
Then Click create page. You can see template(added above).
