title: Prepopulating survey in Surveymonkey with previous year's survey answers?
body: <p>We're sending out the same survey to many of the same participants again this year. Since it is long, we would want to have all of their previous year's answers already filled in, so they would only need to mark any changes that happened throughout the year.</p>
  
  <p>Is there a way to do this?</p>
  
  <p>I've read about prepopulating answers using custom variables in the URL, but this seems to only be useful when prepopulating a small number of responses, not the entire survey.</p>
