I usually will just utilize a statement in the Section Expert to filter the data I want for that group, so if I want to only include ""A"" and ""B"" but not ""C"" for the field that is used to group, I would type Groupfield = ""C"" to suppress, since it is a suppression statement, not an inclusion statement. Another example is for testing for that field being empty, nothing else needed --> ISNULL(Groupfield)
