How do I save the information I fill out on my employee review form without being completed?

If I send the employee evaluation form that I created to our managers, how do they fill it out and then save it? Meaning, if the manager starts to fill out the review form, but doesn't finish it, can they save it somehow so they can come back to it and finish that employee's form/review at a later time? 

You may enable the Auto-fill option for the form so that the form filled information will be stored in the browser storage. When the form is opened again, the filled information will automatically appear on the form.Please be noted that this information can be accessed only when the form is opened on the same browser in the same PC. However, since the information is stored in the browser storage, it the browser is reset or the cache is cleared, the information will be lost.

Alternatively, you may also consider using the session parameter method so that the form filled information will be stored as a session in the JotForm servers. The user would be able to access this information from any other PC and browser. Please refer to the guide below that can help you with this.
