@DanielWickens I am working on deploying the Signal Management Solution. I am starting with existing pole data but will have to manually add the signals and cabinets. I set up a couple intersections with test data to explore how the solution works in various situations. One issue that I ran into is where I have an existing signal and existing cabinet and want to add the signal as a related record to the existing cabinet. I have tried adding the signal to the cabinet in the editor map and the experience but the only option I see is to add a new signal feature, not a signal feature that already exists in the map. The only other option I have found is to copy the GlobalID from the signal to the cabinet through the attribute table. I don't think copying the GlobalID would be a viable option field data collection. Is there a way to add an existing signal feature to an existing cabinet without creating a new signal feature? What am I missing?
