unable to locate customized command

A former admin created a customized command (called it command1) under Organization Unit. User can see it under any OU when they login to the arwebhelpdesk site. I am trying to delete this command. However, I am unable to locate it. I logged in as aradmin in the arwebadmin site. Went to Customization\Customization Tasks and then select Organization Unit. From the command list, I did not see the command there. Any idea how I can locate it?

Thanks
