Event Reports

We would like an Event  Search and/or additional information displayed for Events similar to the Search/Manage Volunteers option. We have an event with 100 volunteers and we are allowing groups and individuals to register.  We would like to see the Group the volunteer is registered for in addition to the existing information displayed.  A report to list Events with Group and/or Value restrictions would be helpful as well as the ability to export the information shown on the Search/manage existing events.
