There is an app to improve the usage of templates and make it easier. No need to copy the content of the page into a template.
The Page Tree Creator will give you the possibility to use any Confluence page as a template and it is even possible to use multi page templates. Check it out on the marketplace (available for Cloud, Server and Datacenter)
