So they basically delete all the listings and import the new list? I guess that would be a simple solution.
I already went ahead and installed Connections Pro and some of the add-ons, and it’s working great. But I did see on the forums for a similar plugin that if you can keep the ID the same, it would overwrite the data. Would that also work for Connections Pro? If so, it might be possible for us to add that ID # in our Access DB.
