Default 6DOF Rigid Body Motion Solver - Defining both centreOfMass and centreOfRotation

Verse is on a distinguished road

I've tried defining both centreOfMass and centreOfRotation inside the dynamicMeshDict, as follows:

centreOfMass      (0.4 0 0.1)
centreOfRotation (-0.5 0 0.1)
After doing this, I recieve an error message as follows:

I see that from the sixDoFRigidBodyMotionState.C code that the solver will default to centreOfMass if the centreOfRotation isn't present:

    const dictionary& dict
            dict.lookupOrDefault("centreOfMass", vector::zero)
    Q_(dict.lookupOrDefault("orientation", tensor::I)),
    v_(dict.lookupOrDefault("velocity", vector::zero)),
    a_(dict.lookupOrDefault("acceleration", vector::zero)),
    pi_(dict.lookupOrDefault("angularMomentum", vector::zero)),
    tau_(dict.lookupOrDefault("torque", vector::zero))
But surely there should be a way I could define both in the same test case? Including the effects of gravity is significantly important for my test case (but I also need rotation), so having these two variables as separate is very important.

Thank you.
