The folks over at Sims 4 Studio, a non-official modding site, have just released a new version of their modding tool that allows for the creation of poses and animations; something we sorely need for the game.
Until there is a pose player mod created for the game, all poses and animations created using this method are default replacements. Release notes for this version can be found here, and a tutorial that shows you how to make a Sims 4 CAS Pose .package using this program, can be found here.
