Searching the QR site for flights in 2022, it appears that 360 days is the farthest ahead a flight can be booked. Is there any way to book farther ahead? QR call center perhaps?

The reason I ask is I have PHL-DOH-SYD booked for early October 2021 and I doubt that Australia's borders will be open by then. QR cancelled my original PHL-DOH leg on a Friday and moved that flight to the next day. I have not yet accepted this change and hope to leave the reservation untouched until late September. Then I'd re-book for late 2022 (I'm assuming QR will continue to have reasonably flexible re-booking terms/EOC for Australia flights as long as the border remains effectively closed). I'd prefer to re-book for October 2022, but with the 360 day limitation it appears I'd need to book both the outbound and return flights for no later than late September 2022.
