I really can't think of anything that does that off-hand. I think MAYBE the old Compu Live software did that, as i remember it had a channel offset function. If you have a MyDMX device that can be upgraded through the Store.dmxsoft.com, that would be the suite 1 software in the list of applications. Or If you are on Facebook, i'd join this group and ask the pros what they know of that will do it.
