The ability to create custom animations for the G3 characters, rather than having to key frame all of the custom animations ,why can't the G1 (Body Puppet) be modified to work with G3 because it seems to be the same angles or possibly be able to record direct movements as in Iclone's (Direct Puppet)?

I really need a way to freely move body parts while masking others that require rhythm for simulating the playing a guitar,drums and other instruments.

I thought CTA3 would have this after seeing that it had free bone characters and items,its nice to be able to preview the movements in real time in composer mode but why not a way to record the movements.
