I believe they do this over east. When on a SID out of Perth and told to cancel and maintain a heading due to inbound traffic, a simple instruction such as "we're looking for height not distance" or vice a versa "we're looking for distance not height" would be great. We probably have in excess of 60 knots to play with which we could use at speed ranges of 140kts to 200kts which would make quite a difference to our rate of climb or ground speed depending on what your after. Therefore everyone wins as we'd clear the traffic alot sooner.
Cheers
