Is there a master page option? I don't want to have to recreate every page if I make a change. Currently I create a template page and save it then add content. When I go to the next page I opent he template, put my new content in and then save with different name.

Now I am working on changing the look of my site. I would not have to move everything, just change the menus lets say. in my current case I have to create all new pages...
