Will this ever be possible? I'm so sick of having to call to rebook travel. It often means that my AS itinerary just gets canceled and I get throw on VA or some other carrier.

It's a reservation, it should matter in the system where it was made. I can do this on every other airline I use pretty much and they all use the same 1960's technology that AS always talks about.

Business travel gets booked on travel websites on not on AS. This company needs to learn about it and fix the problem.
