Just a quick FYI...
The computer management custom action does not work out of the box. It throws an error that it could not find a file or command named "mmc compmgmt.msc". I went to the custom action section of the GUI console and changed the call from "mmc compmgmt.msc" to just "compmgmt.msc" and refreshed the console. It works great now!
