DEFINE_SDOF_PROPERTIES external moment

I need to apply a new force / moment to my UDF file which describes the motion of an object: Mass matrix is defined and only zz rotation is allowed. This object is like a pendulum, doesn't rotate about it's CG.
Now I want to add a moment to the rotation point (defined in FLUENT dynamic mesh GUI, as CG). For that I want to apply the following macro: prop[SDOF_LOAD_M_Z],
but in this case my moment force changes with the rotation angle of the object, and FLUENT doesn't allow me to input the following function:
How can I add these force to DEFINE_SDOF_PROPERTIES ?
Thank you in advance
