Linking Channels and Functions in Building View

The ability to link group objects to group addresses by dragging actuator Channels on to Functions is a real time saver.  However, if a manufacturer has already defined the channels in a certain way that does not fit with the current ETS6 Channels - Functions linking scheme it will not work.

One example that comes to mind is the Zennio actuators.  "Outputs" are grouped together in one channel, and the different outputs are sub-folders inside the channel.  These sub-folders cannot be linked to a function.

It should be possible to link sub-folders of a channel to a Function in the Building view.
