In Jira, I would like my employees to create an issue that already is complete and closed. The purpose of creating the issue is purely for auditing purposes as an official record that the incident happened and was already taken care of. There is no need to put the issue into "Waiting" or "in Progress" status. If it is going to have a status at all, it should just be "Complete" as soon as it's created. Is there a way to do this?
