I would suggest installing and using Justin Hunt's Snippet (Atto) tool. https://moodle.org/plugins/atto_snippet
You could create a snippet of your text format template, then tell each lecturer to add it to their own course page, making amendments as needed. That way you only have to make "one" item and let them do the 300 plus "page" entries.
If you already have the Generico or PoodLL filter installed, you could use them the same way.
