Change order or hierarchy of wikis

Is there any way to change the order or hierarchy of wiki pages without deleting them and adding as new wiki or subwiki?
I am talking about something similar to the way you can play about with pages and change so called "Attributes" such as which page is to be seen as a pages "parent" page

I am looking for a way to move "Wikis" up and down a hierarchy like this one:
Wiki
- Sub Wiki 1
- Sub Wiki 2
- - Sub Sub Wiki A
- - Sub Sub Wiki B
- Sub Wiki 3

Thanks
