you can also do with with elastic audio by instantiating the varispeed plug-in on a track, then dialing in tempo changes in the tempo ruler. (if you're using a other tracks that are tick-based you'd have to disable them.) prior to adding tempo changes, change the track timebase to ticks. after that you can enter tempo changes manually or using the tempo events window. you can also directly edit the tempo ruler events to program specific pitch/tempo variations you're looking for. commit the effect when you get what you want so you can change the session tempo back to normal. sorry, no shortcuts for this.
