I think the idea is spoken beautifully by the image.
Note the "Approve" button has "L2" in the corner. All of these Change Requests are awaiting approval, but only the second one down can be approved by the viewing user, and this approval is at Level 2 of the approval tree.
A similar feature exists on "Service Tasks - Quick Actions" so some of the code exists already.
|What problem will this feature solve?:|
When a Change needs the approval of the person viewing at the current "Level" of approval.
