How to modify options for Approvals

Hi,
I have created a form in a Zoho Creator solution. Approvals for the form was automatically added by Zoho Creator. It has a feature with two options - Approve and Reject, using which I can either approve or reject a submitted form. How can I alter this feature to have three options - Reimbursed, Added to accounts and Rejected?
