We are currently completing our fiscal audit, and the auditors are raising a flag around manager signatures if the manager is the one providing the service as well.

Is there a way to restrict the manager signature to another manager if they are also signing as staff?

We have a couple working managers that may also provide supports some, from time-to-time, and others more frequently.  Currently, they can sign as staff and then as manager and we are looking to see if the system can force or restrict someone from signing as both roles.
