Feedback for each test condition

[stackmeer]

Is it possible to have a feedback box for each test condition so that the participants can explain and justify their grading for each signal. I set up a 'finish' page after each 'mushra' page in the .yaml file to try and get feedback that way but the listening test terminates as soon as the participant hits 'Send Results' after writing their comments. As far as I am aware, there is no obvious way to get comments for each grade for each test condition. Please let me know if this is a possibility.
