As a Confluence Space administrator I would like to be able to create public pages within my space

When managing a large space/ organization it would be a good feature to be able to share viewing rights of pages with people outside of the permission scheme of the page tree / space. 

The way it is currently done within our organization is to set up two top-level areas. One public and one private within the same space. This approach means a lot of copy-pasting between the two areas to keep them in sync, which creates a lot of manual work for space administrators.
