Unfortunately no. But I will certainly add an option, now that you asked, to be there just in case… 🙂
Drill-down is automatically determined by the PK-FK custom or built-in relationships. One way to avoid it is to exclude participating keys from the current query. For instance, assume you have an Order with a ProductID foreign key. If you exclude the ProductID from your query, there will be no drill-down to the related Product when you run it.
