I’d recommend Emerald Coast. Don’t quote me on the specifics but I believe Emerald Coast says that are 14 basic subject areas where TMAATS can come from. If you take the course, they cover this in great detail. They also recommend you have 2 stories for each type of question. After taking the course and their zoom sessions you get really good at categorizing each TMAAT so that you can access the best story from your database to fit the question.
