Support for broadcast wave files

I would be really helpful if FL Studio could support broadcast wave file formats such as W64 format or the RF64 format. The biggest difference is that the wave files have a 64 bit header so they can be a lot longer. It seems FL can't export more than 2 gig wave files, but with ordinary wave files it should be able to output 4 gig wave files (so even that would be a step up). Mostly useful for radio work and podcast work. Now I have to splice them together.
