1. When you are signing a workflow, you can add one or more countersigns with authorization and send the workflow to those countersigns before you really sign the workflow.

2. Open an incoming workflow in the Inbox.   In "Delivery order" field, click "+",  a blank record will be added for choosing a new countersign with countersign check on the right hand side. 

3. Click "Done" to send out the workflow to the countersigns first.  After all the countersigns are completed, the workflow will be sent back to your Inbox and you can consider how to do next.
