Help with Microsoft Word?

Is there a way to see if someone copied a document in microsoft word (any version). I'm trying to convince our school to go digital however their main concern is students copying and pasting or just duplicated homework assignments. Is there any way to track/check if a student had done such a thing inside of the document? Maybe even a plugin to to insert some kind of code or something that can be checked by teachers? Thanks for the help everyone! :)
