No presets for the group

Describe the solution you'd like

It would be nice to get presets from all member actuators (heaters and coolers) and expose them to the user. Whenever the user selects a preset on the group, the preset should apply to all members who have that preset

Describe alternatives you've considered

None

Additional context

Watchout for when 2-way sync will be implemented, as setting a preset on a member may force a different temperature on it, thus making the system enter an infinite loop without proper guarding
