Workflow Stock Report

Can a workflow stock report be created? I created a custom report pulling in the two workflow data views but the WorkflowTransactionIfApprovers table only brings in the participants that have already approved, can the participants who are yet to approve be added to this as well. That way the report can show who needs to approve the workflow. If no one has approved it just shows blank. I have attached my custom report and a picture of my SQL code.
