I'd like to do the same thing that Tanguy described.  I'm trying to figure
out the syntax to this within the workflow editor, but can't quite get it
right.  In your example Dannon, would you just set ${dataset_name} as the
"Name" for your "Input dataset" to capture the input dataset name as a
variable? When I do that and then try to run the workflow I get the
following error:

Error - <type 'exceptions.KeyError'>: 'dataset_name'

KeyError: 'dataset_name'

Perhaps I'm missing something obvious?
