apply template in LibreOffice Writer to existing document

Question

is there a way to apply a template to an existing document?

It only seems to work when I create a completely new document, and i don't want to copy&paste everything.

I'm searching for the same solution. The only thing I've found is a LibreOffice extension to do it. I just tested it and it worked, only I had to add the .oxt extension after downloading it.
