Rotate bones in one plane for elbow IK?

Hi All,

is it possible to make my characters’ UE arm IK solution limit the rotations to work in only one plane, to better approximate a human elbow bend?
By default the Two Bone IK just rotates the bone any way it wants to to get its solve but that is not so useful when doing an arm.

This is for an VR setup with tracked hand controllers driving the IK.

Cheers
