Suppress Volta Starting Repeat

[keith Luke]

Is it possible to suppress the a volta starting repeat?

The following code generates a repeat in front of the g1.

  \set Score.voltaSpannerDuration = #(ly:make-moment 4/4)
  \repeat volta 2 { g1 ~ }
  \alternative {
    {
      g4 r8 g8 d'4 c4 ~
    }
    {{ g2 \repeatTie r2 }}

As an alternative solution, is it possible to generate volta brackets as markkups?

Thanks,
