Conditional Name Mapping combining a Project Variable & constant?

Instead of using project variables for specific departments, etc, you can build your different department lists in Excel sheets and read them from there.  Your test would be designed to run with data from certain columns and not specific values. Then all you would need to do for each environment is rename the tabs so that the one you want to run is TestThisOne (or something better lol) and the test would execute with those values.
