You are on the right track.
Keep in mind that once you have something that works, save a template with those styles so you can easily base new documents on those.
If you have to use the organizer, look at the vba code in my Add-In. You need to do multiple copies of styles that are based upon one another to get a good transfer, AFAIK.
(That has been true since Word 97, at least. I have not tested on Word 2016 or later because multiple copies of styles when you have the organizer up is so easy.)
