I just talked to FedEx today about requesting that a package be held at the hub. They have to make the first delivery attempt and then you can make the request. I asked why that was and he said that until they deliver to you, or attempt delivery, the package is still considered the property of the shipper. But as soon as they make 1st delivery attempt, it becomes your package which allows you to make changes to delivery address or request for it to be held for pick-up. As long as the OP makes the request for you, it should be fine.
