It's not that bad really. First, while I've never compiled any statistics on this, I would be comfortable saying that your modified version will usually work with a new version of AR. Of course Softrak may decide to make inclusion of the Job # a defined option in which case the problem disappears. And even if the report doesn't work, it's only a 20 minute change every 15 months or so (longer the first time admittedly).
