for the life of me i cant figure out how to add my custom motions to any of these folders and get them to work. I've tried for hour bashing my head up against a wall. I'd like to speed up my work flow and love the features of masking and recording stacked motions on the time line. if anyone knows where i can get a tool or if there is even one avail i'd love to know. 

You can add to the Motion Puppet, but not the MixMoves.
