Even though Page break after/before name and description leads user to think it wil happen with that group line, it will actually happen after last/first line of that type is printed.
So if I have 3 group header lines and I set Break Before=True on 3rd, It will happen on 1st. So for compatibility reasons, this has to remain the same, but please add some sub property ie.: “Force break”, which will force the break after/before that particular line and not somewhere else.
