Structured global configuration values allow you to place GCVs into a group. You do this by creating a template containing the GCVs that you want in the group, along with their default values. Then, you can create instances of the template with the click of a button. Designer 3.5 supports adding, editing, and displaying Structured Configuration Values in the Driver and Driver Set GCV Preference pages. The Structured Configuration Values can also be used on the Shim Parameters and the Job Parameters pages.
