Lookups are still not availableĀ as the bound parameters

No, problem. I'm not that familiar with energy efficiency ratings so every suggestion is more than welcome šŸ˜‰. I prefer Github issues for feature suggestions so I can have them in one place.

You can check the control I created atĀ

Feel free to say if it's what you expected or suggest an improvement.

I plan to do it as soon as they enable Lookup bidings.
