The vast majority are told what you were told.
Just a quick update. I was successful recently (Feb 16) with an agent who I feed segment by segment for one of my booking from yyz to Per with stop over in SIN for Dec-Jan. So just keep trying and it is possible. It took her a while as she need to keep restarting her system. She even waived the booking fees.
