Textspan issues.

[Pieter Terpstra]

Dear Lilypond friends,
Doing a Textspan gives me some difficulties.

I would like to see the word pizz. only once in the bi=eginning and not 
repeated on the next line 
and also would like to have the \draw-dashed-line to appear on the last end. Is 
this doable?
Thank you so much in advance!

Apologies for my bad English!

Example:
\version "2.18.2"

\paper {
  ragged-last = ##t
}

global = {
  \key d \major
  %\numericTimeSignature
  \time 2/2
}

\relative c' {
  \global
  \override TextSpanner.bound-details.left.text = "pizz. "
  \override TextSpanner.style = #'dotted-line
  \override TextSpanner.dash-period = #0.5
  \override TextSpanner.padding = #1
  \override TextSpanner.bound-details.right.text = \markup { \draw-dashed-line 
#'(0 . 1) }
  \textSpannerDown
