multiChannelAssociation and endpoints

Reviving this instead of starting a new topic.

I have run into this issue when trying to do direct associations to the different channels of an Enerwave A-wave Dual Relay (ZWN-RSM2-Plus). According to the Z-Wave spec, an endpoint association is specified by (e.g. 0D:1, 0D:2). While various remotes and switches (Zooz ZEN34) have multichannel association capabilities listed in their clusters (0x8E), Hubitat drivers actively prevent you from specifying association node ids for multichannel endpoints. They seem to be validating the node id against the current Hubitat node list and invalidating anything with a ";" character. Right now, the only way to get a multipoint node endpoint ID into a device is to use the Z-wave tweaker port from SmartThings

Can drivers for devices with multichannel association capabilities start to allow them?
