BusinessListBase with root object

hi,

   I am using CSLA3.8,and I found BusinessListBase's collection item are only child objects,but some times,we need root Objects to a list and show in view(DataGridView),In DataGridView we can edit these root objects.so how can i do that?you may suggest me that you should use EditableRootListBase,but in the C# Business Object book,it said EditableRootListBase if for  immediately commit the changes?

Is there any way to use root objects list like BusineesListBase? thank you
