You explained yourself fine - cut and paste what you put here into an email to your UNIX SA and he/she will understand what you want to do. Of course, that doesn't mean you can get it - it's usually a Security issue - accounts get locked automatically and normally the UNIX SA isn't the one who makes that policy. But it doesn't hurt to ask.
