Agreed.
Also, that might be why the call centre agents insist it's not available - I've got a feeling that if their system can't do the route all in the class you want, it just says it's not available. I had this trying to book WLG-AKL-LHR in business, where the first flight is economy only.
NickB's suggestion of building the route up segment by segment is the way to go.
