As AutoCAD Electrical currently works, a wire that is shown on two drawings passes its wire number from the source dwg to the destination dwg using source/destination signal arrows. For some reason, the same doesn't happen with any Wire Number User Attribute values (W01USER, W02USER, etc, etc.) associated with that wire number.
Please expand the API to allow Source/Destination arrows to pass along all wire number information between the wire segments, including WxxUSER attributes associated with the wire number. The way I see it, relative to AcadE wires, the wire number acts as a "TAG" and the WxxUSER attributes should act like "DESC" or "RATING" attributes. On both ends of the wire, the user may want to use these WxxUSER attributes as descriptions to show polarity, phasing, voltage rating or conductor color, (among other things), and may want to leverage this attribute relationship to do other things. Because wire numbers carry through signal arrows, this WxxUSER attribute value should update between Source and Destination, if changed. If the user doesn't want to show it on the destination-end, then the option to hide the attribute is always available, but they retain the ability to use the data. The more attribute data we can add/show/use/pass, the better.
