Hi @Todd Thoms ,

If you have HR agent workspace, it's easy to do it :

Using HR Service Delivery Agent Workspace you can add an approver or substitute missing approvers for cases that require approval.

1. Navigate to All > HR Case Management > HR Agent Workspace.
2. Locate and open an HR case that requires approvers.
3. Select Add Approvers from the list of UI actions (tabs at the top of the form).
   
4. Select replacement approvers or add new ones.
   
5. Select OK.
6. Select Save.
