I guess - even if the OLCI machines don't work - there is nothing to stop one person completing "normal" check-in at a desk, getting the BP, and asking them to put a note, not to move the other passengers in the group. Not sure if this does anything in practice, but they ought to be less inclined to move people that want/need to be sat next to someone already checked in.
