mock-rpmfusion-free/nonfree and rawhide/F14

Hi there, is it possible to update the RPMFusion mock config to take into account that RPMFusions "rawhide" is F14 and Fedora's rawhide is F15? At the moment building for target fedora-rawhide-x86_64-rpmfusion_(non)free results in F14 RPMs taken from the RPMFusion and F15 RPMs taken from Fedora. Fedora's has mock configs for F14 seperately. TIA, Felix
