I have found out that this is partly possible with the re-iterate button. But then people that have completed the survey will not be reset. What I am looking for is the following: a way of completely re-initializing the token table: all people at not invited, not started, not completed. The only option could be: keep token or renew token. Default is keep token.

A tool for :

• Set the token to submit=N/Uses left=1
• Set the corresponding response to submit=N/lastpage=1
  At the same time.
  By token, or by tokens checked (+ filtered token when we have a solution)

+1

You can now batch edit tokens.
