"Allow the original Ik effector to be used as an offset when the aux effector is constrained. This process is currently highly unpredictable. Either the constrained limb will only partially follow the master object or it will follow accurately but there is no way to animate the constrained limb.
If the IK limb, mostly the arms, simply had a group node above it, this group could be constrained and the original limb would be free for re-positioning/additional animating. The HIK is so close to being an incredibly adaptable rig but little points like this cause massive headaches."
