Yeah, you couldn’t simple copy paste, the code would have had to be altered. It was the concept of what I think might need done.
I can’t give you an exact example as I do not know exactly what is being entered in the zipcode field. It would also take me a few hours to come to a final solution with testing. This would be custom programming that I’d have to charge a fee for. The thing is, to pull this off, the core Connections code would have to be altered which mean you would never be able to update Connections because if you did you would lose the custom zipcode sort. Currently there is not a way to pull this off in an update safe way.
