repeat and dynamic

[Gianmaria Lari]

Have a look to the following code. Please note that each line contain
the same notes but different dynamic information:

\version "2.19.40"
{
  a'-4 \p \< g'-3 e'-2 c''-5
  a'-4 g'-3 e'-2 c''-5
  a'-4 g'-3 e'-2 c''-5 \!
}

Is there any way to write the previous code using a repeat? Something
like this (that of course does not work):

\p \< \repeat unfold 3 {a'-4 g'-3 e'-2 c''-5} \!

Thank you, g.
