Support DMVPN and MPLS Objects in Custom Auto Grouping Layout

NetBrain's custom auto grouping layout currently does not support defining DMVPN and MPLS map objects as part of the layout configuration, so these objects cannot conform to the automatic grouping and positioning structure applied to other device types. This enhancement would allow DMVPN and MPLS map objects to be included as definable elements within custom auto grouping layout rules, enabling consistent automated placement alongside other network elements. Customers managing WAN topologies with DMVPN and MPLS clouds would benefit from consistent, automated map organization without manual repositioning of these objects.
