  Hmm, I don't really know how to do this in k., in ser/tm there is a
  global variable called rmode which can be used to determine what kind of
  route block you are in. I quickly checked your sources but could not
  find it, so maybe it was removed or replaced with something else (this
  is a pretty old thing).
