Reporting across projects

Hi ,
I would like to design a report template that could show me the work items across different project areas. I tried to use "COMMON_SNAPSHOT" for the parameter dataset. But the resulting report shows me the workitems of either the current project or all the projects. But I would like to generate the report on an individual project basis.
Any help is appreciated.
Thanks,
Bharath
