In the Project Server 2010 SDK, there are a set of Solution Starters that provide additional functionality in Project Server 2010. The ‘Bulk Edit’ Solution Starter would allow you to update multiple Projects at one time, which would then be reflected in your Project Center Views.
It is a little tricky to get working (deployed) correctly, especially if you have firewalls. Plus, once it’s working, it can be a little temperamental at times, but it would save the monotony of opening, updating and publishing each Project individually.
By default, once it is deployed, the tool will only be visible to the Administrators Security Group members as an additional icon in the Project Center Ribbon.
