Project with Time and Labour - Overriding approver issue

 Hi All

As part of our client configuration, timecards from OTL are approved by the employee's direct HR supervisor. However, in case he selects and overriding approver, the approval goes to the overriding approver instead.

As per the seeded view of the Overriding approver LOV, it displays only employees whoes HR job is mapped to Project job 'Manager' in the Job mapping screen. Business wants that some employees who are not mapped as manager to be also available in the LOV.

Is there any way to achieve the same specific to a project role as an exception?

Regards
