I created this simple element that seems to do the trick. Basically, for each page, it checks to see if the group matches the previous one. If it is different, it assumes that it is the first page of the group and does not display the title.
'At the top of the module window I created a "Module-Level Variables".
Dim current_group As Integer
Dim temp_group As Integer
Private Sub PageHeaderSection_Format(Cancel As Integer, FormatCount As Integer)
current_group = Int(Me.MyGroupID)
If current_group = temp_inst Then
Me.PageHeaderSection.Visible = True
Else
Me.PageHeaderSection.Visible = False
End If
temp_group = current_group
End Sub
