Bone Setup/Animation of a Group of Layers

[typo]

I've been testing out Moho demo, which I'm really liking right now. I've created a basic character in Moho, through a series of layers to get the image I want.

I wanted to test bone setup on the legs, but all I get is the rotation of the layers along the pivot specified by the bone.

For example, my character set-up is:

Character Name > Legs > Top Leg (Side View) > (2 layers) Leg; Foot

Now if I put the Top Leg (Side View) folder into a bone layer, I get the rotation issue. If I put Leg into a bone layer, then it will deform and animate realistically (well, kinda real- bah, I'm blabbering), leaving Foot behind in its original position.

Is there a way that I can get both working at the same time, or do I have to create one layer with both foot and leg and animate it like that?

Thanks.

Nevermind, I just refined the model to have a layer per element/piece (Arm, Leg, etc.). Thanks anyways.
