I am modeling a residential space where OA is supplied to a corridor, then transferred via the door undercut to make-up for the toilet and kitchen exhaust fans. I want to set the air transfer using the OS:ZoneMixing object, which according to this link it supports.

My question is: does Openstudio has a visible object that I can drag and drop to the zone? If not, then do I have to add ZoneMixing directly to the IDF using a measure?
