How does Ansys Twin Builder implement different simulation steps for subcircuits

  I am currently doing a system-level NVH simulation of a motor under real-time control. The motor housing state space matrix simplified model (SPM) obtained from modal analysis is exported to Twin Builder and placed in a subcircuit to calculate the vibration of the motor measurement point.
  The global step size is set to 1~10us, and the subcircuit step size is set to 50us, but the subcircuit step size does not take effect during actual operation, so the simplified model (SPM) calculates the motor displacement with the same step size. This results in a very long calculation time.
  Therefore, I would like to ask, how can I set the simulation step size of the subcircuit to be inconsistent with the global simulation step size, so that the simulation speed becomes faster?
