Full GDR Property Support for Control Variables in Golden Engineering Studio

NetBrain currently does not clearly support all GDR properties within control variables used to segment rules by site information, and when a needed property is unsupported, customers must modify behavior through a plugin, which carries risk of unintended side effects. This enhancement would extend control variable support to cover the full set of GDR properties natively, removing the need for plugin-based adjustments. Customers managing site-based rule segmentation would gain a more reliable and lower-risk way to configure rules, reducing dependency on custom plugin changes.
