I have a Google Document that was created using default styles. Our company has since created some Google Docs templates to use for styling. I'd like to apply the template's styling to this existing document, which is quite long, without having to copy/paste each heading and body text element into a new document. Is there a way to do this?
I found this Google documentation on how to create a new document from a template, but I couldn't find anything about how to apply template styling to a pre-existing document.
