Please, if you have no clue whether your suggestion is useful, resist the urge for "first post", and wait if someone gives a useful answer. If after half a day the question is still unanswered, you could always come back with an answer. Remember that your answer will be archived and could show up on a site search. Wrong answer reduce the usefulness of site searches.
