Anonymous responses but track by respondent

Anonymous responses but track by respondent

Hello.

I love having the ability to create an anonymous survey by unchecking the box "Require participants to enter information" in Settings > Collect audience info. But when I do that, there is no identifier attached to each response, which means in the downloaded report I cannot track an individual user's responses across multiple questions to correlate data. I would like to see a random number attached to each user's responses in place of their name in order to anonymously track each user from one question to the next. Being able to track a user's response is really important to understanding how different experiences are related to satisfaction across multiple areas.
