Can a plugin control which string in a TAB staff to write a note to?

I believe jeetee to be correct - it uses the cmd function. Which I suppose I could try, tho I am trying to do this in pure 'batch' mode. And certainly I could be missing something. In Fretboard's addNoteWithCursor() function there is:

        for (var i = 0; i < fretView.strings; ++i)
        cmd("string-above");

Here is what I've tried:

    function addNewForcedToString(measures, notesToWrite, pitch, string, cursor) {
        console.log("In funct addNewForcedToString");

        cursor.setDuration(1, 4);
        notesToWrite = measures * 4; // assuming 4/4 time sig.
        var oNote = newElement(Element.NOTE);

        console.log("oNote string: ",oNote.string, " | pitch: ", oNote.pitch);
        //console.log("oNote pitch: ",oNote.pitch);

        cursor.rewind(Cursor.SELECTION_START); //<-- I am presuming we have selected a measure
        if (cursor.element.type === Element.CHORD) { //<-- am presuming the cursor is sitting on a chord element in score.
            var chord = cursor.element;
            var notes = cursor.element.notes;
            var numNotes = notes.length;
            console.log("# Notes in Chord:", numNotes);
            var oNote = newElement(Element.NOTE);
            oNote.string = string;
            oNote.pitch = pitch;
            console.log("oNote string: ",oNote.string, " | pitch: ", oNote.pitch);
            curScore.startCmd();
            chord.add(oNote);
            curScore.endCmd();
        }
        else {
            console.log("Cursor not sitting on a chord");
        }
        // RESULT of the above test is that pre-setting a string number on the note object
        // has no effect on where Musescore places the note on the TAB.
