Include End-User Desktop Devices in Bulk Add-to-Device-Group from Map

NetBrain currently excludes end-user desktop devices from the bulk 'add to Device Group' action performed on the map, even when they are included in a multi-device selection alongside other device types such as switches. As a result, desktop devices must be added to a Device Group individually, one at a time. This enhancement would extend the map's multi-select add logic to include end-user desktop devices, allowing them to be added to a Device Group together with other selected device types in a single bulk action. Customers managing environments with mixed device types would benefit from a consistent, efficient workflow for building Device Groups without manual, one-by-one additions.
