DOAS and dummy zones

Dear eQuest users,
I am dealing with a building that has a MZ centralized ventilation
system (no AC nor heating but with economizer and heat recovery
capacities), and independent AC systems per zone.
Is there a way to model a DOAS that supplies OA to the different other
than creating a dummy zone and defining a PSZ to supply the required
ventilation air to this zone, and then have other zone PSZ systems get
its OA from this dummy zone?
Thanks,

Xavier - I've recently used the "Heating / Ventilation System" Type,
assigned it to a mechanical chase zone, un-installed the heating element
of this system, turned on the Economizer and ERV functions, and in
assigned the individual zone system's OA as supplied by this "Heating /
Ventilation System."

But be cautious of what the .SIM report says under the ATTN tab for the
equipment...
