I currently have 252 Blogs on my network. I would like

I currently have 252 Blogs on my network. I would like to be able to delete certain pages and posts that were made on all the blogs. Is there an easy way I can do this without visiting all blogs individually as the admin?

There is no file structure (for the users blog) on the File Manager so I can't just delete files.

I have used the Multi-Site Content Copier to push out a "new" version of a page but it does't replace the old version so now I have to delete these old version of the pages I pushed out.

Please help me as soon as you can.
