If you're using 2.13 you can span a hyphen between the stanza and the
first lyric syllable via a scheme engraver:

\version "2.13.31"

#(define (stanza-lyric-hyphen-engraver ctx)
   (let ((hyphen '()))

     `((initialize . ,(lambda (trans)
                        ;; if 'stanza is set, make a hyphen before anything
                        ;; else has happened
                        (and (markup? (ly:context-property ctx 'stanza))
                             (set! hyphen (ly:engraver-make-grob trans
                                                                 'LyricHyphen
                                                                 '())))))

       (acknowledgers
        (lyric-syllable-interface
         . ,(lambda (trans grob source)
              ;; if a hyphen has been created, set the first
              ;; syllable acknowledged as its right bound
              (and (ly:spanner? hyphen)
                   (ly:spanner-set-bound! hyphen RIGHT grob))))

        (stanza-number-interface
         . ,(lambda (trans grob source)
              ;; if a hyphen has been created, set the stanza
              ;; as its left bound
              (and (ly:spanner? hyphen)
                   (ly:spanner-set-bound! hyphen LEFT grob)))))

       (stop-translation-timestep
        . ,(lambda (trans)
             ;; clear hyphen at end of first timestep
             (and hyphen
                  (set! hyphen '())))))))

  \new Lyrics \with {
