Pinning Hands?

  • New to Poser, coming from Max, Maya, and Houdini- looking to add another tool in my kit.
    Poser looks promising for some work but I haven't seen anything about pinning hands down- basically switching from FK to IK and back. It seems it's either that the hands are driven by IK the whole animation or by FK. Would be nice to be able to pin hands down for a few frames then release them.

    Is that something Poser can do?
