startpoint of decrescendo hairpins

[Ewald Gutenkunst]

Hi,

I have a question to decrescendo-hairpins and lyrics: 
How can I change the startpoint of the decresc, to begin at the note an not at 
the beginning of the lyric?


\version "2.14.1"

melody = { d''2 c''2   |  es''1  }
text = \lyricmode {a long  hairpin }
upper = {c'1    | b4  b b b }
dynamics = {s1  |  s4 \>   s4 s4 s4 \!   }

\score {
  <<
        \new Voice = "mel"  \melody 
        \new Lyrics \lyricsto mel \text 
        \new Staff   \upper
        \new Dynamics \dynamics
  >>
}

greetings
ewald
