lauraneb Hi
Not sure as to what you wish to achieve. You can always refer to documentation excerpt to see how landing page can be set up
If wishing to assign the similar template style for another menu item, You can assign via Templates: Edit Style > Menu assignment
Or copy the landing page to make a landing template for article ?
Yes, You can also "duplicate" the template style and customize settings accordingly. Thereon, Assign different "Menu" as methodology would remain the same as seen in specific documentation excerpt
