Not sure if the following example helps, however it demonstrates using the binding context of the selected item in conjuction with the navigation path.
This works for 1 level i.e. /A(selected_item_from_list)/B, however it sounds like you need to do something like "/A(selected_item_item_from_list) + /B/C/status" which I'm not sure you can do in a single step?
