See the last successful build date on project group homepage

On the project group summary page, it could be good to see the last date for which the build was successful for each project of the group
In my case, we have a lot of projects, they almost build everyday but for some of them, the last date the build was successful is 3 weeks ago. And I can only see it if I go on the "builds" tab for each project and I do not have time for that. And I can't be notified for each project and even if I was, I would have to keep emails, etc...
