What do you mean by editing the document directly? Could you elaborate on this?
If I update a template and go back to a document that used the old template, it would keep the old style/formatting. Conversely, if I create a new document based on the new template and copy/paste everything from the old document, it retains all of the old style/formatting and I have to update everything manually within the document.
In both of your suggestions (editing doc directly & recreating using new template), do you mean that I would have to manually change the style/formatting within the document as opposed to it automatically changing them in either case?
One more question: is there a way to apply a new formatting to all instances of a particular style within a document? For example, if I copy/paste a document with custom paragraph styles into a new template, can I change all instances of a particular paragraph style (or list style) to a new style? Such as changing all instances of “imported style 1” to “heading 1” at once as opposed to manually changing each instance one at a time.
