Adding note names to a language

[Br. Samuel Springuel]

I would like to add the basic solfege note names to the english language 
module so that I can enter music (mostly chant) using solfege and then 
use `\transpose` to adjust its sounding pitch to create a midi file 
which can be used for practice.  So far, I've done this by editing 
define-note-names.scm to add the appropriate lines.  While this works 
fine locally, it makes for files which are not portable.  Is there a way 
to add pitch names/aliases in a more portable fashion (i.e. within the 
music file itself).

%%% BEGIN SNIPPET %%%

\version "2.19.80"

\language "english"

% I need something that will define these note names like adding 
        (do . ,(ly:make-pitch -1 0 NATURAL)) etc. in the appropriate 
place in define-note-names.scm does

music = { do re me fa sol la ti do }

\score {
    \new Staff {
        % note the mixing of the solfege names with
        % a traditional english note name in the following line
        \new Voice \transpose do d' \music
    }
    \midi {
        \tempo 4 = 120
    }
}

%%% END SNIPPET %%%
