Modifying a Structure (Speed Mode)
When a structure is built using Speed mode, you can adjust the scope or hierarchy at any time by clicking the Modify structure button in the Structure toolbar.

On the Modify Structure page, you can:
Add/remove projects or add project filters
Add, remove, or modify work item levels and group levels
Reorder work item and group levels
Filter or sort a work item or group level

Once you've made your changes, click Apply. The structure will update automatically.
