There is a way to add more layers to an animation, however I would be careful in using that feature. In the Animation palette window there are three tabs at the top. Keyframes, which shows the Dope Sheet. Layers, where you work with the extra layers. and Animation Sets. And next to that is a Drop down that is labeled Layer: (Down Arrow) BASE. If you click on Layers it opens the options for the Layers function. Please read the manual for all the options. The BIGGEST thing to remember is that currently layers has some bugs which have been reported and are awaiting being fixed.

What you want to do is click the new button and a new layer will be made. It will be in REPLACE mode. I suggest you leave it in that mode to minimize the bugs. It is also best to make the layer the whole length of the animation, until you get use to how it works and know how to fix the bugs. When in Replace anything on the Layers below the layer you are working on will become non-functional. So if you make a figures chest move in and out, then anything on the Base layer with chest in/out will be replaced. And if you go to the Base layer and try to change a part that is affected in the Layer above then the dial will not move. so if you have the arm bend in the new layer, you can't bend the arm in the Base layer. However you CAN twist the arm in the Base layer as that has not been replaced.
