Well, it wasn’t there on my system, so it took me awhile to find it, but that gave me the info I needed to do so. It was actually under the Local Application Data directory:
%LOCALAPPDATA%\UnrealEngine\4.1\Saved\Config\Windows\EditorGameAgnostic.ini
aka
C:\Users\(username)\AppData\Local\UnrealEngine\4.1\Saved\Config\Windows\EditorGameAgnostic.ini
Thank you very much for the help!
