The ability to "import" or "Batch Add" dial plans when editing an outbound route would be a decent time saver.
I have a "Local Calling" route that has 84 entries to define my local calling area.
Cut and Paste works but it is very time consuming. Being able to import from a file or add from a multi-line text control would reduce my time significantly.
In my case I would add the list twice. Once for standard dialling, second to strip long distance codes entered by mistake.
