SteamVR Wrist Offset

I am using the SteamVR animation blueprint nodes InputAnimPose and SetWristTransform to set a UE4 hand skeleton in a VR project. It works very nicely right out of the box. But, I’m trying to adjust the location of the hand mesh in world space, and to do so accurately I need to know the offset that the SteamVR node is applying to the hand. Is there a convenient way to get the wrist bone position that SteamVR is going to apply to the hand mesh in the animation blueprint? I’m about to dig through AnimNode_SteamVRInputAnimPose.cpp, but it feels like this is something that’s probably already exposed somehow…?
