We are also "feeling the hurt" of not being able to carry the input dataset names through a complex workflow. We are also very interested in a solution similar to what Dave Walton has proposed,. Dave, would it be possible to receive a copy of your modified code? Does it work when there are multiple inputs? Ideally we would keep the names of datasets that are run through complex workflows the same as the workflow progresses. Sample mix-ups are a common scare, and with the current default naming it is not far fetched to see someone accidentally associating the end result with a different sample number. Thanks much, Ann
