Action Center Approval Task

Hi,

I want to create a process that does multi-level approval.

For example if tier 1, needs 3 people to approve a loan application my process must loop back to same suspended form to get each approval for each person. so basically when they click approve on the suspended form it must log that they have approved the loan and go to the next person keeping the Approval suspended until all 3 people left there outcome.

How can this be done?
