How to reassign Expense Report pending with terminated project approver?

Hi All,

We have a requirement in Expense module where ‘Expense approver’(Project Manager) left the organization and the expense report is pending in his/her queue.

We want to know, is there any delivered approach where system can check following flow to reassign the expense report to correct approver?

1. Check new approver is assigned for the associate >> Route the expense report

2. If new approver is not assigned, Check the Project Manager/Proxy Project Manager >> Route the Expense report

I checked Escalations and Re-routings functionality but this requirement is not cater in there.

Please share your thoughts.

Regards,
