EnergyPlus HVACCurveFitTool for chiller EIRfPLR curve?

EnergyPlus' Chiller:Electric:EIR requires a quadratic performance curve for it's Electric Input to Cooling Output Ratio Function of Part Load Ratio (EIRfPLR) curve. This curve represents efficiency as a function of part load and lift.

Is it possible to create this quadratic curve using EnergyPlus' HVAC Curve Fit Tool?

I can create the biquadratic curves for CAPfT and EIRfT using the tool, but I'm not quite sure how to create the quadratic EIRfPLR curve.
