Approve automatically if the same approvers presents in next level approval

Hi all,

I have a requirement to approve automatically in a approval process.  Below is the scenario

1.  Consider we have 4 level of approval process and assigned approvers are same in the all level of approval process.

2.  Once the approver approves in initial or First level, workflow should automatically approve  the next level approvals if the same approver present in next levels.

Thanks in advance for suggestion
