ZHA group members - one member change state, others follow

Dear all, wouldn’t it be possible to configure the ZHA groups in a way that if ANY of the members change state (ON/OFF) then rest of the group would follow?
I can have all members to change state when I change the ZHA group (ON/OFF) but if I change only one member, then rest of the members do not care.

This would be usefull for WALLSWITCHES - this way we could setup 2way/3way switches without having to have AUTOMATIONS run in the background to trigger other switches

If you want to switch all of them, trigger the group.

That is clear - but I cannot assign a wallswitch what it needs to trigger - it just triggers itself. Then I need to have automation that is reacting on the event of state change and then trigger rest of the wallswitches.
