changing notehead in themiddle of the chord

[Matevz Jekovec]

I'm trying to change the notehead in the chord in the same voice, but it 
doesn't work. The output is
lexport.ly:37:41: Error: syntax error, unexpected MUSIC_IDENTIFIER, 
expecting DRUM_PITCH or NOTENAME_PITCH or '>':
      \bcr g'8 \btr a \bcr b g e' e d < g, \bt
                                              r e' > | \bcr g a b g e' 
e d e |   % 3 not good

Is this a bug or not implemented yet?
