This would streamline the process of querying differen't criteria without having to establish multiple queries for each hypothetical'. Currently, the only way to accomplish the equivalent of this, would be to store criteria in the sort field, so that it does not interfere with the query results, and then pull it into Criteria from the Query Fields drill-down.
