Menu Builder URL structure

[will83]

Menu builder is a great functionality, but I can't figured it out why URL structure is based on page builder rather than menu builder?
In my point of view, it would make more sense if we could define a simple "identifier" for each page (ie : "my-page" for a page named "My page") and build architecture in menu builder (or make it optional) --> the URL structure will be generate base on the menu builder hierarchy.
Actually, when moving an element, we have to define a new parent in the page builder to follow the menu logic?

Just to be clear, you're asking for page permalinks to be based on the menu structure instead of the individual pages' structure in relation to each other.

Closing as wontfix.
