CBECC-COM space functions for kitchen areas with no exhaust?

I'm modeling a small restaurant in CBECC-COM. There are two distinct areas of kitchen in this space - each served by its own HVAC unit (necessitating two separate spaces). One area is served by an HVAC system and features a cook line with kitchen exhaust. The other area is more of a "back of house" kitchen prep area with no exhaust system.

I'm getting performance analysis errors because i have not assigned a kitchen exhaust system to the "back of house" kitchen prep area. It's telling me to add an exhaust fan or revise to a different space function. There doesn't seem to be any other appropriate space functions. The only one that seems close would be "Commercial and Industrial Work Areas - Low bay." Anyone have any suggestions?
