How to send emails from (groupname)-owner@yahoogroups.…

As the owner or moderator of a group, am I able to send an email to a group member that will show up in their inbox as coming from the (groupname)-owner@yahoogroups.com? I know members can send email to that address and it comes to me as an owner or moderator, but I cannot figure out how to do it the other way round. Can this be done only by a group owner and not a moderator?
