How to apply acceleration PSD on p_face in random vibration of workbench?

      This question follows the previous one "Questions regarding Boundary condition setting and Random Vibration Analysis (pressure excitation)". The blade shroud and hub face are fixed boundaries, and random loads with acceleration PSD of airflow on the pressure surface and suction surface.
      Pressure PSD loading and solving was previously resolved by defining p_face and APDL commands.
      Now my question is how to load the acceleration PSD? Can I still use the previous command stream but add a different PSD type?
