MIDI Mapping for Pioneer DDJ-SR

Hi I know that mapping is available for the DDJ-SX but I want to buy the SR model. Is anyone aware of a mapping available , don't want to do it manually as I'm likely to make a right mess of it . Also if and when a mapping comes out will it work on older versions of Cross ( I use 2.4) or will it only be for the most recent version. Many thanks Jim
