You can set the color of the layer and establish layer groups in the timeline. You can organize your parent-child layers by stacking them in order. My parent layer is almost always at the bottom or the top of a layer stack. You can also organize layers by properly naming them then reveal only the layers you want by using the timeline search bar. I do that a lot. For example, in this comp, I am adding some graphics to a day-for-night shot and I cannot keep all the graphic elements stacked on top of each other so I start each layer name with Left Window and I've set the layer group color to orange to make it easy to select them all.

If all the components of the character you are animating started with the "Bob..." then you could easily isolate all of the body parts and the layers should be in order so the overlaps.

Short and simple: No.
