I'm trying to figure out how to set the font style for an entire word document, exactly the way it's done by choosing a style preset in the menu:

Since I've already made a macro that converts the entire document word for word, what I'm trying to accomplish with this is changing all the preset tiles (Normal, No Spacing, Title, Heading 1, etc.) to match this existing preset, and not the old presets (with the old fonts).
Is this possible, and what object do I modify to accomplish this?
