Using the templates in Visual Composer it is possible to save a copy of a page and then place that into any other page.
Open and edit the page you want to replicate
Select Templates, Save current page as a template
Enter a name for the template
Add a new page or open an existing page
If creating a new page, click Visual Composer
In Visual Composer mode is the Templates button
Select Templates, click the template you created
Template contents are added to the page
If you are adding the template to an existing page with other rows of content then it will be added to the bottom of the page. If you click on the name of the template you created twice by accident then you will most likely end up with the template contents on the page twice.
