A Tracker permission would be useful that behaves similar to "have access to all artifacts assigned to or created by group". But instead of granting access to the artifact to all members of the assigned user's group, it should only grant access to the assignees and submitters of the usergroup.
Currently it is not possible to restrict some users to only see the artifacts they are involved in (assignee and/or submitter) and manage them all via one usergroup.
With the permission "have access to all artifacts assigned to or created by group" all members of the usergroup would see the artifact. Additionally, if a assigned user is in more than one usergroup, all members of all those usergroups, the assignee is part of, would also see the artifact.
There is the option "have access to artifacts they submitted" which sounds almost like what I would like to have, but assignees do not seem to be considered there.
The only solution, which came to my mind with the current possibilities, seems to create a user group for each individual user und set permission to "have access to all artifacts assigned to or created by group". But that's very impractical with many users.
Alternatively, is there any other way to achieve this?
