Based on my knowledge of this program from using it every day. You could use the unity version to create your own body parts and animations. With that being said, I don't believe that those kinds of animations are even in the scope of the road map for this as it clearly was built for platforms and side strollers (Which is why I purchased it). Also, all of the packs for this (DLC) are for just that as well. Obviously I'm not part of the dev team, just wanted to share with you my experience with it. The dev will answer though, they've been awesome with their public relation responses.
