How to copy a document?

Is there a function to copy a document?
There are 9 tables, copying and moving each one is not an option, I was thinking of using it as a template.
There is a move function, maybe add a copy function?

Yes there is! When you open a document, there is a “Duplicate Document…” option under the “Share” menu, which will copy the document:
