Insert or remove levels in a structure
You must have write access to the structure to insert or remove a level. The insert action adds a level between the selected object and its parent object. The remove action removes the selected element’s parent object one level above and attaches the element and all its siblings to its current grandparent object two levels above.
Search for the structure you want to edit and click Open.

In both cases, removing or adding levels, the element may split due to effectivity cutback. If you are not able to remove an aligned occurrence, contact your administrator.
