Different fees in energy dashboard

Hi everyone,
energy dashboard in HA is awesome, but would be nice to have ability to add multiple entities into energy cost and divide entites into 2 groups: price for Wh and price for some time, fe week/month etc.

in our country we have at least 5 fees calculated by kWh and 3 fees added to cost once a month

Big thank you for great work which you are doing here

You can do the first part using a sensor that has the cost.

The second part has been asked for many times already.
