Assignments Tab
Most of the assignment operations are performed from the Assignments tab, shown in the figure below.

The Assignments tab contains a multi-object properties grid that consists of two subpanes: (1) the Assignments pane, which lists the user-defined assignments; and (2) the Properties pane, which lists the set of properties for each user-defined assignment.
You can use the Assignments tab to add, rename, delete and duplicate assignments, and to view and edit assignment properties.
