Yes? If I am understand you correctly, you are asking how to add a new template to your wiki. You do that by creating it the same way you create any other page. The only difference is then you enter the name of the page to create, include "Template:" in front of the rest of the name. For example, "Template:Featured" creates a template called "Featured".
