Is there a way to add property value to non-leaf item in list?

Is there a way to add property value to non-leaf item in list? I think this requirement is meaningful, if not necessary. However, found it undoable in the grid view of list.

At this time, there is no way to add a property value to a non-leaf item in a list.
