Tools and techniques are described for selecting member sets for generating asymmetric queries. User interfaces provided by this description may include representations of different dimensions that include respective members. These dimensions define hierarchical data structures against which queries are run to generate requested reports. The user interfaces may include representations of members associated with different dimensions, with members from different dimensions arranged in selected orders. The user interfaces may also provide selection tools that activate symmetrical or asymmetrical rendering modes for constructing the query. In the symmetrical rendering mode, the query cross-joins all of the members selected from one dimension with all of the members selected from the other dimension. In the asymmetrical rendering mode, the query cross-joins the first-ordered member from one dimension with the first-ordered member from another dimension, cross-joins the second member from one dimension with the second member from another dimension, and so on.
