Support for Adding Custom GDR Fields to the Built-In Device Report

NetBrain's built-in Device Report currently displays only a fixed, predefined set of GDR attributes and does not support adding customer-defined or customized GDR fields as report columns. This enhancement would allow users to select and add a customized GDR attribute into the built-in Device Report alongside standard fields. Customers who rely on customized GDR data for device tracking would benefit from consolidated reporting without needing to build and maintain a separate custom report.
