How can I create reviewer functions?

Hello Im trying to create an application form.

Once a form is submitted, does jotform have the ability to send notifications to reviews of applications and automate acceptance and denial letters?s

It is somewhat possible to automate an approval workflow.  Here is a detailed guide on how to do so:
