New Benefit Rates update issue

Content

We have recently updated the rates for some of our benefit plans. I had processed 'Administrative' Life event for all employees so that new rates will be updated. But we had quite a few employees with manual rate override in their plans (Override through date = 12/31/4712). The rates did not update for these employees. We had to manually change the Override through date to (Administrative LE date - 1) and  run the Admin LE again for the new rates to get updated.

I would like to know the best approach to update the rates in such cases. Requesting your inputs.
