Etihad Multiple Destination Booking - Fare bucket question

[Melbin]

Hi all, wondering if anyone has any experience booking multi-destination trips on Etihad? My problem is I don’t really want the ‘breaking deals’ fare as I want to be able to bid for an upgrade on one or two of the legs. The flights suggested once you type in your cities don’t give you the usual fare choice options like a normal return flight to a single destination would. They're all just grouped together, so I’ve no idea if they’re under that fare code or not. First world problem I know…

Anyone know how to get around this? Preferably without resorting to having to call Etihad, which as anyone with any experience knows is pretty soul destroying…!

Thanks
