Ad Hoc Site Grouping of Selected Devices for Map Layout Operations

NetBrain map layout tools currently operate only on individual devices or on the entire map; there is no way to designate a user-selected set of devices as a temporary, ad hoc grouping scoped solely to layout operations. This enhancement would allow users to select a set of devices and group them into a site group, so that auto layout or other layout operations can be applied to that group as a single unit rather than to each device individually. Customers building and organizing complex maps would benefit from faster, more predictable layout control over logical clusters of devices without manually repositioning each one.
