Alternate Approvers for specific people/specific approval stop (using T&E as an example)

Looking for input on how to handle the following scenarios using delivered functionality:

1. We have a Dept supervisor who wants to delegate their approval authority for their direct reports to another person. Delegation will not work because if they’re also setup as an Expense Approver, it would auto-reassign those transactions as well. And we cannot override the Supervisor on their T&E Profile because the Employee Sync overrides this.

2. Somewhat similar to #1, an agency wants a specific person approving the HR Supervisor stop for a list of 10 people. This specific example is they want the CFO approving all Section Director’s travel, and when the CFO submits an ER it goes to a specific person to approve. Again, we cannot just update the Supervisor on their T&E profile because the Employee Sync overrides this setup, and Delegation will not work because we do not want it all-encompassing for that person in the module.
