Hi,

is the following what you want?

\version "2.18.0"

\score {
  <<
    \new PianoStaff
      <<
      \new Staff = "upper" { c'''1\arpeggio  }
      \new Staff = "lower" { c'' 1\arpeggio  }
      >>
      \new Staff = "feet" { c'1\arpeggio }
  >>
  \layout {
    \context {
      \Score
      %% Is not the default for Score -> IR
      \consists "Span_arpeggio_engraver"
      connectArpeggios = ##t
    }
  }
}

HTH,
  Harm

P.S.
Please post a compilable example next time.
