Bulk Tracking Number Updates

It'd be great if exported csv files of TN's contained the field names & values required for bulk TN update via uploaded csv.

This would enable an efficient download of entire list, make a few edits where changes required, then upload the same file back to CTM.

Currently- this isn't possible, because there is minimal alignment of the import/export files. Field names are different. The TN's on export aren't even in the right format. Route ID values aren't in the exports (and I could only find out what they are, via a support ticket).
