While I don't think you can do it with footage like AE is, you can certainly ease keyframes via the keygraph editor. I think maybe version 8 or 8.5 added bezier handles that you can drag on your own rather than number based easing. Simply select the keyframe, then the easing method will open up and you can select based on your preference. For a fast then slow, I always used a TCB interpolation, the inframe is -2 and the outframe 1 in the tension.
