Is it possible to save and continue a jotform later with cookies?

We have quite a long form and sometimes the user will be part way through completing it when they realises they need more info. Is it possible to have a save button that will just use a 24 hour cookie to retain the data locally so they can complete it later ?

Yes, that is already possible using our AutoFill Feature that allows users to save and continue their jotform using their browsers cookies.
