Yeah, you're looking to duplicate data here, which isn't how Crystal works.
It's a bad database design I guess, and you'll need to do something on the database, perhaps you can create a Union All View:
select 'Class" MySource, Class, field2, etc... from table
union all
select 'Test" MySource, Test, field2, etc... from table
This will provide the data duplicated and you can group by the MySource column.
