I wrote a custom driver but did not include commands to set associations: [RELEASE] Zooz ZEN32 Scene Controller (community driver).
I could certainly add them or add the commands required to make it work with a community app if that is what you alluded to above, otherwise I'm not sure why a driver dedicated to association specifically wouldn't work (aside from the fact that this device probably supports more than most people would expect...).
Alternatively, Hubitat appears to be slowly adding association as a built-in feature, but right now it's only available for a few devices. They might eventually get around to this, or perhaps a more general way to do this for more devices...
