Yeah, if you have a list that has the ID and the other values you want, you could then populate the data in your form when the user picks a person - here's a made up sample that uses an XML file instead of a list, because that way you can preview it and try it. Save the file locally, right click and select design, then preview. Employee IDs in the sample are 1, 2, 3, and 4.
