Splayed stems

[Caio Barros]

Hi, is there some way to write splayed stems? (I don't know if this is the correct name, but it is how Finale name it)
The best I could do so far is this:

\relative g''' {     
\once \override Stem #'rotation = #'(45 0 0)
     \once \override Stem #'X-offset = #2
     \once \override Stem #'Y-offset = #1
     \once \override Stem #'X-extent = #'(0 . 0.5)
     ges4*1/3
     g4*1/3 
     \once \override Stem #'rotation = #'(-45 0 0)
     \once \override Stem #'X-offset = #-2
     \once \override Stem #'Y-offset = #1
     \once \override Stem #'X-extent = #'(-0.5 . 0)
     a4*1/3
     e d c
 }

but the result is not very pretty and I have to change every time. Very annoying.
