How does one add "Organization" as a field to the sort list in the event report template? I have found how to add custom fields but not system default fields.
Version 4.6.8 Joomla
If you mean 'how do I show the Organisation that is the Employer of the person attending the event' then you need to see if the 'Current Employer' field is available for that event. "Organisation" is not a field per se. It is a Contact Type.
