How to handle AME approvals where multiple people have same limits

We are implementing AME for requisitions and during our testing are finding that if two users have approvals limits for a requisition (ie same dollar value & cost centres) the requisition must go to both users, even when one is the preparer

e.g. Employee 1 has $5000 approval limit on cost centre 12345 Employee 2 has approval limit on cost centre 12345

Employee 1 creates the requisition and submits, the approval hierarchy that the system builds is employee 1 and employee 2, the requisition must go to both before being approved.

Any way around this?  We have the option user can approve checked. When we were using the purchasing hierarchy this was not an issue.
