Provide a means of a central project list from multiple project sites.
Each Project web site has a project list / assignments. We would like a means to have one central list for independent multiple project sites. You can do this if you put all the project sites as sub-sites under a top site, but then you run into security issues. So for security reasons, have to create each Project site now as top site but then each site has its own project list. Just would like to have one place to go look at all the project tasks from multiple project sites in one place instead of having to go to teach project URL.
