In our team we are two persons responsible of writing User Stories and we always cross check each other's User Stories to improve quality and make sure everything is done correctly.
Would it be possible to add to the transition rules for trackers that only a certain person or assignee can change the status field? Both of us are in the same user group.
Example
Person 1 writs a User Story and assigns Person 2 as Reviewer
Person 2 Reviews the User Story and changes its status to Ready, but only the reviewer (Person 2) can do that to guarantee that the User Story has been reviewed.
