Feature Request: Redefine utility_meters and tariff sensors

[FragMenthor]

Ability to redefine utilitty-meters and tariff sensors in integration configuration without having to delete and create everything again. For those who have more than 20 devices (I have more than 100), having to redefine 3 utility meters for each device and 3 sensors x 3 for each tariff is an Impossible task. Each time I add a new device I have to redo everything....Thanks for this great integration!!! Should be official.
