Many sites have pages which have a very similar layout for internal pages. Instead of adding a new page you can clone an existing similar page which will copy all the settings, modules and content.
You can do this by navigating to the page you would like to clone and clicking the icon below.
This will load the same screen, adding a new page with all of the same settings. You will need to change the page name and file name as a minimum before you can click Save & Continue.
Tip: If you want to select a group of pages which are set as a hierarchy, you can select the parent page and tick before clicking Save & Continue.
