Site Properties Field Management and Accurate CSV Import Mapping

NetBrain currently does not provide a way to remove, rename, or otherwise manage custom fields under Site Properties once they have been created, and importing Site Properties data via CSV can create new duplicate fields instead of mapping values into existing fields, leaving the imported data unpopulated. This enhancement proposes adding administrative controls to add, edit, and delete Site Properties fields, along with a CSV import process that correctly matches columns to existing field names and populates the corresponding data. Customers managing site metadata across large environments would benefit from cleaner field administration and reliable bulk data imports, reducing manual cleanup and rework.
