How to Dynamically update the Approval Workflow based on the supervisors that are getting derived

Summary:

We are having a Job level hierarchy approval, in which we are having an exception scenario as mentioned belwo

User 1 will be having a job level of 10 with approval amount of 1000

User 2 will be having a job level of 20 with approval amount of 2000

and User 3 will be having a job level of 30 with approval amount of 3000.

The hierarchy will be user 1 reporting to user 2 and user 2 reporting to user 3.

We would what an exception in such a way that if user 2 is raising a requisition of amount 4000 it should get auto approved also if user 1 is raising a requisition which of 4000 which will be routed to user 2 as user 2 is the manager of user 1 the requisition should get auto approved as the user 2 is having an exception of 4000 dollars where based on his job level the amount is 2000.
