Ports multiplicity in IBD

[Gengis]

I am modelling a cable. The cable highest hierarchy block has input and output ports with multiplicity [*].
I need to define one, two, three, etc... wire cables from the father block. For implementation, I need an IBD where each input port is connected to the corresponding output port (Through these ports flows "electricity", which has two values: voltage and current). The ideal is the possibility to define for n ports a connection one to one, no idea if this is possible!!! One option could be to have an IBD for each cable with a given number of cables (one IBD for 1-wire cable, other for 2-wire cables, an so on), but also in these cases... How the ports[*] (with multiplicity [*]) from the parent block could be defined for 1, 2, etc... for each of this IBDs diagrams and how do they could be retrieve or associated... ??? If I want to model cables from 1 wire to 100 wires... Should I have to maintain 100 IBDs??? Just for the complete idea... in the first basic model cables need just to equal voltage and current from in and out ports, but for further stage cables will model resistance (according to length, area, etc) and other phenomena.
