It would be nice if we could define a heat pump as a piece of equipment but have a second piece of equipment like a ductless split or fan coil either as a secondary part of that equipment that can be placed on a separate drawing (or a different part of the same drawing) or if we could link them in some way. The goal would be that once you circuit the heat pump, the same circuit would automatically be assigned to the fan coil which may or may not have an additional load. Then when drawing a homerun from the fan coil, there could be an asterisk or a note saying to "circuit via associated heat pump".
