There are mods for a 2 mode Peak, but with the development of lights using QTC i would venture to say its less probable but only Curt R or Robyn S can answer that for sure.
I have been reading some older Peak threads on the forum and there were plans for a multimode switch but then seems it vanished, i do think this could be interesting but with QTC in the lights now its impractical.
I am curioust though about it and am interested in knowing what happened with that switch (which could also fit what you are looking for)
