Template - copy an entire document as template

Hello there ,
I’m studying psychology and every semester I organise my notes in the same hierarchy.

I have created a document that is the template for the new subject…but…

The problem I have is that I cant copy and paste the entire document/template in one go, not sure how to ?

is there an easy way to do this?

You have to turn everything below “subject template” into slots and tag “subject template” with ##Automatically Add Template, then tag any new doc with ##subject template. Any other combination will sadly result in only applying direct child slots (see Allow templates for templates/inheriting slots from added slots)
