The action process allow you to specify input and output parameters. However when you call the action process inside the UTW Distribute Action tool, the subsequent step in the workflow does not reveal the output parameters
Image 1: Process Argument

Image 2: regular subsequent step shows output parameters (if placed beyond normal "Perform Action" step)

Image 3: no output parameters when using the Distribute Action from the UWT

Would be great if you can fix this in a future release of the UWT.
