A query can define a range that is included in any criteria you want. The criteria does not have to be locations. It can, for example, be a list of attributes.
Example
A range can be orders for computers with selected top-of-the-line features, that are listed in the TADB database as attributes for a Bill of Materials.
These orders can be identified through a query for those attributes.
The query that includes the range of features can be used as the range source.
Steps to select a range as a source include.
