They are already visisble in Studio in the base game section and you can recolor them. The only thing that is missing are the finger- and toenails categories. You could use another category meanwhile until an update will air. You may also want to keep in mind that the Studio team does have a regular life with daily tasks. I'm pretty sure that an update will come when their time is right. Since this is a free tool, everyone should respectfully wait until an update is released.
