Can the Duct E+ object be used to make a AirLoop demand-side bypass?

How is the E+ Duct Element typically used? I was contemplating using it as a Airloop demand bypass, similarly to a plant demand bypass with an adiabatic pipe. Tried to add it in between an exiting AirLoopHVAC:ZoneSplitter and AirLoopHVAC:ZoneMixer objects, but got yelled at by E+.
