I sent the a/c dct DIDGO simply to save the a/c track mileage (and therefore time, money etc etc). REDFA was not on the flight planned route and CLN would have involved the a/c flying more out of its way.

In order to help the pilot route to the desired location without delay and multiple button-pushing you could offer the magnetic track required and the distance to run as per MATS 1.
