you could always highlight them by ...it it shift click and drag or...I do it without thinking, but just Highlight them in the time line ,right click to copy scroll down , move to 101 , then right click to paste scroll down. I think that'll work, you can then open the graph editor to mess with the transition between the cycle if you wish. Someone post if I'm way off I just used Affter Effects for about 4 days and my keys are all off in my head:)
