How can I restrict a small portion of users in a project to only see issues they created or are assigned but let everyone else in the project see all issues? For 1% of users I need to restrict them to only issues they for which have responsibility. This will be less than 0.1% of the issues.
In Jira this was done by setting "Security Level:AssigneeAndReporter" for all issues in the project. Within the security settings I listed all groups, except those accounts that are restricted, has having normal project access.
