Our Pages (shared version of My Pages)

I would like a Team of users to be able to work collaboratively on pages to create a shared 'My Page'

The use case would be to build a UX Report page that contains all the tables and commentaries which go into a Management or Board Report. 

Different members of the team could contribute to their area of responsibility and produce a share result.  It need not be concurrent working, allowing the users to lock the report as they are editing it would be sufficient.
