Reference a parameter in a different workspace than default

I am executing a Copy Data Management step which references a literal parameter (NOT in Default workspace) to get the scenario value. However, I am receiving an "Invalid Parameter" error when trying to use the parameter even though I confirmed the parameter is named correctly and has a value. 

However, when I created the same parameter in the Default workspace, the Data Management step executed successfully. 

In a Data Management step, is there a way to denote which workspace the parameter should be coming from? I tried something like: workspace_name.|!Scenario_parameter!| but no luck. Is there any documentation on this?
