Joining polygon edges

Using Create Area Feature or Trace Mode, is it possible to create a new area polygon (call it polygon 2) with different attributes adjoining an existing polygon (call it polygon 1) using part of the margin of polygon 1? This would avoid having to trace around the common boundary to create polygon 2. I have more-ore-less achieved the result I am after by cutting out islands but is there an easier way?

Thanks in anticipation
