Replicate Hue Entertainment Group Behaviour?

Hi,

I have been using Zigbee2MQTT now for a while and love what it does!

I have set up my devices (mostly lights) into groups.

I was wondering if there was a way to replicate the Hue Entertainment group behaviour for devices that support it?

I appreciate that the Entertainment group behaviour isn’t strictly to Zigbee standard, but as far as I can see, there is no way to be able to do this in Zigbee2MQTT…?

It would be nice to have this functionality especially as the DiyHue project now has support for MQTT devices - the two projects could glue together very nicely with this sort of functionality.
