How to output heating gains/losses from zone ventilation in the Airflow Network

I have modeled a naturally ventilated multi-zone structure in EnergyPlus using the AIrflow Network. I've been trying to output the heating gains/losses due to ventilation, however that output-variable doesn't seem to exist in the Airflow Network Outputs. Curiously, the sensible and latent heat gain/loss from zone infiltration, and zone mixing from the AFN exists, but not ventilation...

Is there a reason why this is not provided? And is there another output-variable I can use to calculate this i.e. using the AFN Linkage Node 1 to 2 Average Mass Flow Rate and outdoor and zone temperatures to manually calculate ventilation heat loss/gain myself?

I think I've found the answer here. Somewhat confusingly, the AFN Zone Infiltration output is the sum of ventilation and crack flows into the zone.
