Automatic Approval of timesheets at the resource level

Hi there,

I have a Manager that would like all of the timesheets submitted from her resources (she is both their Resource Manager and Timesheet Approver) to be automatically approved, rather than her needing to approve them.  The tasks the Manager's resources use vary based on client work they engage in so we need to do this at the resource level, not the task level. 

Thanks,
