GENESYS enables you to set two different default sort blocks - one for entities in a single class, one for entities spanning multiple classes - to best tailor the sorting and representation of lists of entities. These default sort blocks are selected by default when lists of entities are shown. You can then easily change the sort block for a given list by selecting from the set of sort blocks shown in the drop-down list at the bottom of the entity list.
Under the Utilities section on Project Explorer, access the Default Single-Class Sort Block option on the right-click context menu in the sort block list. This command prompts you to select which sort block to use as the initial select for lists of entities in a single class. Single-class lists of entities include the entity list in the project explorer, the target list in target and insertion windows, and the entity lists in the diagram toolbox.
