Creating a report with tasks and milestones from more than one project?

Creating a report with tasks and milestones from more than one project?

Does anyone know if its possible to merge the tasks and miles stones of a number of projects into one report?  I have a number of projects that are all for one client and would like to send them a monthly summary report of all of them together (rather than printing off one by one and re-scanning).

All the projects sit within one group if that helps...
