I use Remote Control API to export responses using my application.
I would like to have the export_responses method to convert answer codes "Y" and "N" to whatever I want.
This is possible through the LimeSurvey interface in the "Responses" section, options "Convert Y to:" and "Convert N to:".
I need this because I want to differentiate, in the csv export file, answers that was not responded because they were not displayed to the user (in case the question depends on a specific answer in other question -- conditions/relevance stuff), and answers that was not selected by the user (e.g. in multiple choice questions).
