Yes, but this is tricky enough that I think something should be
added to the docs. Maybe when I have some time I can do that, but
in the meantime, here's the solution:

- Mark

\new PianoStaff \relative c'' <<
  \set PianoStaff.connectArpeggios = ##t
  \new Staff {
    \override PianoStaff.Arpeggio #'arpeggio-direction = #UP
    <c e g c>4\arpeggio
  }
  \new Staff {
    \clef bass
      <c,, e g c>4\arpeggio
  }
