Power consumption calibration

Hi, I have some plugs with power meter and in Zigbee2Mqtt is an option to calibrate power, for some is 4%, other 2.2%, can we archive this on ZHA? Maybe editing configuration?
Also, how can I switch off the led, there is no option for that like in Z2M.
Thank you!

I hope this option will be implemented in the future updates.

Just a bump!
