Yeah it's not super clear how to do it but it changes so much adding a tutorial would be pointless right now. Having said that each "pose" is like 60 or so vbx files working together with the animations to make it dynamic as it is. So adding say doggy before we get our pipeline in place would be a lot of work if we had to backtrack for whatever reason. Playing it safe and doing it right saves a lot of headache later.
Hopefully you understand why it's so limited atm.
