[Feature]: Leave light off when changing temperature/brightness for light groups

[humanBeer]

Is your feature request related to a problem?

I'm always frustrated when all lights turn on when i change the temperature of a group

Describe the solution you'd like

An ability for the slider to check if a light is on before it sends the command to change the brightness/ temperature. Not sure if theres an inherent limitation with groups. Maybe being able to define multiple entities would allow this?

Describe alternatives you've considered

I have given it the label bug as well since I think it sounds more like a bug. But thinking about it, it sounds like it might be because when calling the home assistant service for temperature on a light group, it will change state for all lights in that group? Even without the slider?

I will look more into it when I get the time.

Thanks for reporting.
