So, This feature is needed for speakers and well as lighting items.

We already have two kinds of wires, fixed and bundle.

This can be a third kind of wire, circuit, where the headend can be one, the distribution board or the rack, but the tailend or tail terminal will have a list of all items on the circuit. This way, it can be tracked for circuit loads or circuit impedance using a custom property for wattage in light fixtures, and impedence in speakers.

further more, the wire length feature here will be able to give estimated wire length of full circuit.

In drawing, this shapes tailend terminal will keep storing item info its connected to, but the headend will not change. But this can impose an issue if we try and break a tailend connection.

Or the start terminal and end terminals can match data, example, one item can be added to either terminals once or twice only, the second time it will be acting as a start terminal for circuit moving forward.

This idea may work like POE devices feature, instead of devices for another POE source equipment, we will have devices on a bundle wire cable of type circuit or loop.
