CALayer question regarding sequence of animations

Good evening all...

Using CAAction or CATransaction, can you create a sequence of animation (usually changing a CALayer's property) that occur one after another?

I know you can modify the duration of a single animation using CATransaction, even eliminate the animation all together. You can also group a set of animations, so that each one starts at the same time. However, I want to create a two or more animations that follow one other, without having to resort to a NSTimer or such. I want to be able to create this animation in single code segment (not require timers or callbacks).

For example, I want to create an animation that make a hidden layer appear (aLayer.hidden=FALSE), moves it to a new position (aLayer. position=CGPointMake(100.0,100.0), and then fades it back out (aLayer. hidden=TRUE).

Any thoughts?
