To workaround the picture edit system not being able to export a 32-bit float AAF you could just assembly the location WAVs as per the AAF/XML that is supplied from editorial using
EdiLoad or the PT field recorder workflow functions. The EdiLoad Assembly window does simplify this process, and I'd recommend getting an AAF from Media Composer or a XML from Premiere Pro.
