Come on ladies and gents! Several folks bend his question and offer potential software solutions, but only ONE comes anywhere close to answering his basic question. I hope @Victo can glean what he needs, but he'll probably have to make some assumptions in the process, exactly what he apparently does not want to do. I cannot answer his question. If I could, I'd do so without distractions, at least until his modest question was fully answered. I think we can do better. Just as carpenters measure twice and cut once, perhaps we can read twice and answer once, responding to the question asked. Thank you, one and all.
