Is there a simple way to manage workflow approvals when the approver is out of office?

I don't want to have to go into each workflow and update when my workflow approvers are out of office, on vacation for example. Ideally, I would like the approvers to update the dates they are out of office and provide a delegate for the approvals that are received in this timeframe. Any approvals required during this period would automatically go to the delegate and be replicated across a number of workflows and smartsheets. Thanks!
