Modify relief airflow

Hi, In my project I have made a EMS that controls the fraction of outdoor air based on the concentration of pollutants in the return air. However,I see that even though I manage to control the OA fraction with the EMS, the relief airflow does not change to be the same massflow as the outdoor air flow.

Do you know if I can control the relief? I have looked at the .eed file and I find it as System Node Setpoint,Mass Flow Rate Setpoint, but I dont seem to have something as I have for the OA AHU_OA_CONTROLLER,Outdoor Air Controller Maximum Mass Flow Rate,[kg/s]

Thanks !
