After creating a system, there is simple functionality for renaming a system. To begin, each system is initially named 'System X' where 'X' is number of systems created when 'System X' is created.  To rename a system, move the mouse and hover over the current name of a particular system.  This will trigger a pencil icon to appear; clicking upon the pencil, the name becomes a text input field.  

Any system name can be entered as long as the name is not the same as another system within the same job.  

Pressing enter or clicking outside of the input field will store the name of the system.  The name of a system can always be edited.
