To help with this - we've created the option to preview a precedent before exporting it.
Take an example precedent - on the screen it looks like this:
To preview how it will look on the printed page - click on "Extras" > "Preview the precedent"
This then renders the text on the screen, as it will appear on the printed page - given the options and text you've added to the fields in the precedent.
The picture below shows how you can see what the number paragraph will be of the precedent you're working on, once it is exported.
