You can clone a HubSpot blog post, email, or page to use an existing piece of content as a starting point for a new piece of content. In the design manager, you can clone a template, theme, or module to make changes without affecting pages using the original file.
Clone a blog post or page
Changes made to a cloned page will not affect the original page. If you change the cloned page's template, however, those changes will affect all pages using that template.
Please note: knowledge base articles can't be cloned.
