Inbox items in a thread

Is there a possibility to get inbox items in a threaded view? I know I can get the inbox items with /users/id/XX/mailbox/notes/inbox But that only returns the notes one by one. And I do not see a full conversation. So when I get a note I do not know if the note belongs to a thread or is a single one. Is there anything in the response which denotes a kind of thread id for inbox items?
