I think if you use \VoiceOne and \VoiceTwo you should get what you are looking 
for.  I 
regularly combine hymn harmonies from various sources into a single score and I 
use 
them to achieve that.  Here's a few snippets from my standard file just showing 
the right 
hand (I place all the parts in one file where this came from, then I do the 
score in a 
second one and include the parts in it.)

% lilypond starts
% \melody and \alto are defined above 
% as regular music expression blocks
%

global =  {  \time 2/2 }

Key =  { \key ef \major }

rhUpper =  \relative c'' {
        \voiceOne
        \Key 
        \mark \markup {HTC}
        \melody
        \bar "|."
}

rhLower =  \relative c' {
        \voiceTwo
        \Key
        \alto
}

PianoRH = {
        \clef treble
        \global
        \set Staff.midiInstrument = "acoustic grand"
        \context Staff <<
                \context Voice = "one" \rhUpper
                \context Voice = "two" \rhLower
   >>
}

piano = {
        \context PianoStaff <<
                \set PianoStaff.instrument = #"Piano"
                \set PianoStaff.minimumVerticalExtent = #'(-2 . 2)
                #(set-accidental-style 'piano-cautionary)
                \context Staff = "upper" \PianoRH
                \context Staff = "lower" \PianoLH
        >> 
}
% lilypond ends
