Group multiple trvs with one gui thermostat control

It seems you can group multiple switches, lights
and others but not group multiple trvs with one gui thermostat control

If you are interested, there’s a custom integration available that allows you to group climate entities.

It might be useful for you until Home Assistant supports it natively (if ever).

I second this request.
I have multiple rooms with 2 TRVs each and the ability to group them natively, would be a godsend.
We already have native groups for other things, so why not thermostats?

Thanks for that will give it a go
