chromatic harmonica: number notations?

[Carl J. Weber]

For chromatic harmonica, blow and draw notes are easily notated in Lilypond by customary circled and uncircled numbers placed in proximity to the notes. However, when the chromatic harmonica slide is pushed in (causing to be sharp the note as played without the slide pushed in), the traditional notation was has been a dash below the blow or draw designation. Any suggestions are highly appreciated.
