I see the benefits of simplifying the heat pump option configuration, but how is one meant to distinguish between cold-climate and non-cold-climate qualified heat pumps with the new version?

What about a ccHP checkbox that switches between EPA or NEEP criteria-satisfying low-temperature performance, and more conventional options?
