Approval workflow to be set up based on budget type

Summary: Different approval workflow based on the budget type

Content (please ensure you mask any confidential information):

The client has a requirement where they would request different budget and these are of 3 types, and for each budget type the approval workflow will be different. Is there a way to achieve this using the same approval unit? Reason why we want the approval unit to be same is because all the 3 types of budget request is to be made across same scenario and version for the current budget cycle.
