It is in the rulebook.
Care to point us to that specific rule?

Have you tried doing it yourself through MMB? Almost certainly won't work but worth a try. Next try calling BAEC directly and tell them you want to upgrade a D sector and cannot do it online. (Make sure there is Z availability first.) If you have the correct BA pnr I can't see why it wouldn't work.
