When working with database queries and trying to query specific sources from Prospect Ratings, every available specific source shows every available category to choose from. The issue is not all sources are related to every category and vice versa. It would be extremely helpful if only those categories related to that specific source shows at a selectable option. For example, we have a 'Research Staff' source that is only related to a 'Research Capacity Rating' category. But yet in the database query options the 'Research Staff' source has 29 categories to choose from.
