bump
If "bump" is supposed to be some kind of nudge to get people to reply, please have more patience. You posted only sometime late yesterday, and many people take up to a few days to receive the posts from this newsgroup, and even those who don't shouldn't be expected to reply the same instant they read your question. Also, it's quite possible you won't get any reply (though this is pretty rare) in which case "bump" is going to be seen as nothing more than rudeness, given that if an answer was forthcoming it would probably already have been posted. In such a case, you're better off rereading your request and considering whether you phrased it adequately or can supply additional information to help potential responders.
(In this case, your question looks fairly clear, though it doesn't look like you've spent much time at the interactive prompt experimenting and trying to find an answer on your own.)
