[TYPO3-english] pbsurvey: Save answers across total form?

[Martin Terber]

I am using pbsurvey (Questionaire) to create a multi-page quiz. 
I have a multiple radio button setup, one multiple choice question per page. 

The questions that are answered are saved and can displayed  when users go back per page. However, when going forward afterwards, the answers are cleared. 

Is there a way to configure this behaviour, so that all answers are saved?
