Xact Dialer Using Multiple Caller IDs

Our broadcast system is sending out the same message but for multiple offices. Each office has it's own unique DID. It would be very helpful if the module could mask caller ID on a per call basis rather than the entire campaign. Could you simply add an additional column to the CSV file that tells each call (row) what called ID to use?

This would allow us to simply create one campaign to accomplish our goal rather than creating separate identical campaigns each with their own caller ID.
