Outline: Keeping styles when exporting to Word

This is what I want to do:

I want to use an outliner to structure a piece of text, using different styles to titles in each level. Later, I want to be able to export this outline to Word format, while keeping the styles to each title and having the text structured as a Word document.

I do have OmniOutliner Pro and Circus Ponies Notebook as outliners. I have not found a way for Notebook to do this. On OmniOutliner, I can assign a style to each level, and Word recognizes the styles when I export it to Word format. OmniOutliner allows me to assign a style (Heading 1, for instance) to a line but when I export this to Word format it won't keep the styles unless I use different levels in the outline. The thing is, I am not always able to use different levels, since I want to put body text after Heading 1, after Heading 1.1 and after Heading 1.1.1, on different levels.

Is there some way to accomplish this? I am not even sure I made myself clear here.
