I'm translating a LaTeX document into docx. I have some custom environments in LaTeX, for example "notes". I would like these to appear with a custom style in the docx output. The docx style would be defined in the docx "reference document".

Is there a way to add style instructions in the LaTeX code, to specify the target docx style for a LaTeX environment?

For HTML or Markdown this seems to be straightforwared (like here, using <div> tags), but I can't figure out how to do the same from a LaTeX source document.
