How to email inform all approvers in same approval level that the workflow is denied by one of the approvers?

Hi,

We have a workflow consisting of multiple approval steps in one approval level. Any denial from any step makes the workflow come to an end.

All approvers in the same approval level received approval requests at the same time, so they are informed need to take approval action, but when the workflow is rejected by other people, the rest of approvers receive no email to inform them that no action is needed now. That makes the approvers unhappy.

May I know if there is a convenient way to inform all the approvers in the same approval level about the denial decision from the others?

Thanks.
