tie behavior

[bill wolf]

Good Lilyponders,

The code below achieves my goals.  I'm wondering if it could be done more simply.

\version "2.18.2"

\relative c'' {

  \new Staff <<

    \new Voice { \voiceOne c8 e~ \once \hideNotes \once \override
                       NoteColumn.force-hshift = #-1.2 e4 g8 d'~ \once \hideNotes d4 }
    \new Voice { \voiceTwo c,4~ <c e g>8 \override TieColumn.tie-configuration =
                       #'((2.0 . -1) (5.0 . 1)) e~ <e g>4~ <e g d'> }

  >>

}

The only more specific thing I can add is that I almost always prefers ties in the middle of triads to go up.

Thank you for your expertise!
