Equipment to Equipment Address Auto Populate

Hello! I am new to the forum and just started diving into Dynamo to simplify my teams day to day workflow. I model pneumatic tube systems utilizing duct and duct fittings for our piping and mechanical equipment for our stations and diverter boxes. I am looking for a way dynamo can help auto populate a duct run parameter between two pieces of equipment. Per the attached image, I am trying to find a way to have the parameter SDA_Length auto generate text based on the addresses of the two pieces of connected equipment. For example, once connected, SDA_Length would populate 010-121 for the highlighted pipe run. Is this possible? Thanks!!
