Yes it is a separate Page template file that you can create by going to Merchandising > Custom Templates > Pages.
You can either create a brand new file or copy one of the ShopSite page template and modify it.
You can call it what ever you want as long as it is the same name that you use in the [-- LINK mytemplate --] The file extension doesn't matter. Note that the name should not include spaces.
Also note that you don't have to use the mytemplate format you can just use [-- LINK --] and it will use the format for the link that is specified in the page template that is currently being called.
