Currently, there is no way to indicate that a data device contains more than a single port, unless you add multiple connectors. Creating up to 6 different circuits for a single data device is cumbersome. Revit should add a number of poles parameter to the data circuits. This way we can actually use the "Data Panel".
As of now, there is no way to make this workable. It takes way too much time to use multiple circuits for the same device.
