Peoplesoft Expense approval Transaction Definition there can be only 1 Approval System Adminstrator

The Peoplesoft Expense approval Transaction Definition can have only one user ID, defined as "Approval System Administrator". In case of Routing failure (occurs if an approver is not properly defined and there is no other business defaulting rule in place) approval workflow is routed to them. In our case this usually happens if a supervisor is not assigned to a user profile or if the supervisor is no longer with our company.

In such case we would want the ER or TA to be routed to a team with a specific role and not just to one person. We have a lot of different agencies using Travel and Expense and for all those agencies it cannot be routed to one single person. Is there an alternative to this?
