de Silentio

I am wondering if there is a setting that makes it so each Word document can have custom window settings. For example, I have one document that I want the window size to be 640x480 and have no Ribbon. I want another document to be full screen with a Ribbon. And yet another document that is almost full screen with a Ribbon. Currently Word opens every document with the same window settings as the last document I closed. Any help is appreciated.
