Inform the applicant that the form is already filled by the recommender

Is it possible to let an applicant know when the person they have listed as a recommender has completed a form for them, if the applicant's email address is not embedded in the form?

Is it possible to create a unique link for people to click on that links a particular applicant to an application?

How would you inform the applicant? Is it via email? If yes, the applicant email address should be provided. Otherwise, I don't see any other way to inform the applicant.

It is possible to prepopulate values to the fields through URL parameters. You can use this as a unique link http://www.jotform.com/help/71-Prepopulating-the-fields-to-your-JotForm-via-URL-parameters.
