Compare DWG Files

I just read about a feature in IntelliCAD 10.1 that allows a user to see differences between two dwg files, COMPARE (DWG Compare). I am using Carlson 2023 with IntelliCAD 10.1, and wanted to use this feature, but it says the command does not exist. And I can't find it in the onboard IntelliCAD Help either.
Any ideas, Hivemind?
