In the structure tool as in many other tools there are a button called “Execute task”. This is actually a way to extend the tool with your companies own routines and interfaces tailor made for you. The first view will therefore be a list of available tasks when you click that button.
Hopefully you know which task you should execute by the names they have. When you click on the one you want to run that task will continue the wizard so the steps will differ from task to task. Examples of tasks could be exporting contents, creating sub sites with a certain structure or control all links on the site.
