Does Jotform have workflow/ approval routing feature?

I need to route a form tone person to provide date and approve, and the two additional people to approve the data on the form.

Please see this guide: http://www.jotform.com/help/194-How-to-Assign-a-Status-to-Submissions

This can help you to accomplish what you need,  you will be able to mark submissions as Approved or Disapproved using Hidden Box tool. This is somewhat like an Admin Approval System. 

Let us know if you need more assistance, we will be glad to help you.
