Issue with Requisition Approval setup for approval group

We are done the setup as mention below for Req approval based on department:

1. The approvals are Driven by routing the requisitions to users who are approvers within a specific Department (Cost Center). All the approvers will receive the notification at the same time and anyone approving will approve the Requisition (Parallel first responder wins).
2. We are routing the Requisition by defining Approval Rules based on condition of Department (Segment 3: ) from our Requisition Distribution Charge Account (Cost Center in Cloud) and approval groups (Account approvers with names), with Parallel first responder wins.

All the scenarios provided by business for project and non-project is working fine except the below scenario, where they have one Requisition created with a Line having multiple distribution and each distribution has different Charge accounts with Department being different, And approvers in the Department are different. They want the requisition to route it to all the approvers for both the Departments, but any one from each department has to approve for the Requisition to get finally approved.
