Bentley Configuration Explorer / Switches

I'm using Bentley Configuration Explorer 08.11.09.26

ShortcutCreator

Q1:  Which .cfg file is being appended, and when does my specified .cfg file load?  Or does my file replace the PowerGeopak.cfg?  Please explain the use of -wc switch, is it path only or complete path and filename?

Q2:  When I want to set an additional variable, what would be the syntax?  Add another switch -wsDEPT-STRUCT or append 1st switch -ws_NSI_AGENCY=TXDOT;DEPT=STRUCT   ?
