Multi-Format Export

A lot of the time I want 3 different export files of a mix down. The raw/original format example, 88.2khz 32bit wav (for archive, mastering), 44.1khz 16bit wav (for CD/Car, client), mp3 320 (for reference, client). Why not be able to do all three of these auto-consecutively, or better, at the same time?
