EnsLib.Workflow.TaskRequest Customization Help

According to the Documentation  EnsLib.Workflow.TaskRequest has the following fields...

• %Action
• %Command
• %FormFields
• %FormTemplate
• %FormValues
• %Message
• %Priority
• %Subjext
• %TaskHandler
• %Title
• %UserName

I want to be able to capture the Source, Session ID, and any other Identifiers outside of the Error so it will show up on the Task List.

I am struggling how to build a csp template for me to be able to capture additional fields to send to the Workflow Operation.

Does anyone have a good example outside of what is in the documentation on how to build out a Custom Form for this information to show up in the Task List?
