Security

Greetings.  I'm looking for guidance on whether or not I can add my own Alias Names to an Authentication Source.  If so, please guide me to that location in the GUI.  As pictured, I would like to add an Alias Name called "SQL Query".

Thank you.  I was trying to do that, but because it was referenced somewhere else, kept giving me an error.  The solution was to go back and create a new source, and replace all references to the source with the new one.
