I want to add Reviewer as a field to tasks and bugs, and I want the person assigned as reviewer to become a watcher of the item so they receive notifications.
I found a Reviewer field on one of the configuration screens in Jira, but I wasn't able to add it to my issue screens. So I created a custom field just for the time being. But prefer it to be a standard Reviewer field rather than custom so the notifications will work as they should.
