You have to accept the client order and have it in your client order list in order to send the aux on searches.
Thanks. That detail needs to be noted someplace because after searching guides for the better part of two hours, that part isn't mentioned at all and seriously needs to be brought up.
Finding this information confirmed what I was thinking. Its just unfortunate that you have to keep the client orders on your list to use this method. Taking up space if you're not using premium, unless I have the wrong.
