I think you define cue-during-details as a music property, and then do

\cueDuring 
\withMusicProperty #'cue-during-details #(list '(clef . "treble_8")
                                               '(cue-name . "Vl.1")
                                               `(transposition .
                                                 (,ly:make-pitch 1 0 0))

{...}

I haven't tested this, but I think it works.  See
