Pushback clearance question

[daan_vb 37]

Hi,Just a quick question. I sometimes hear ATC ground give pushback clearance to AI aircraft like this: "Speedbird 435 clear to push, call for start" or something to that effect.However i never seem to get this sort of pushback clearance. I always get "Baby 145 cleared to push, start at your discretion" or something like that. (I can't rememebr the exact wording...)Is it possible to get the first type of clearance?
