I have noticed that when I run a workflow with output to a new history, the data sets used as input to the workflow do not become part of the new history. Unfortunately, if a job fails in the workflow, the "rerun" interface for the job can't access the original data…it needs to be manually imported. While this is a minor annoyance, it becomes quite the pain if you ran the workflow for a bunch of input files. Can I put in a request that input data be imported automatically into workflow run histories, or have I missed something in the workflow run options?
