[galaxy-user] Create workflow with a fixed dataset from data library/history

Hi, I was unable to find if this was asked before, but I have the 'problem' that I want to create a workflow for a specific project. This worklow I want to reuse a couple of times but some of the datasets will always be the same and a few have to be set each time the workflow is run. The way I would like to deal with this is to include datasets from a data library, which are already shared and visible to others. This ensures that the workflow is run with the correct main datasets. Instead of a datalibrary dataset this could also be done by linking it to a history item, which might be more flexible. Is this already possible or else already in the feature requests? :) Cheers, Jelle
