[galaxy-dev] How to set output name programmatically in workflows using the API?

Hi, I would like to use the "Rename Dataset" action with a value base on the input. I was wondering if there is a way to do this programmatically? Searching the list I found this enhancement request that I think could help me, any update on this feature? https://bitbucket.org/galaxy/galaxy-central/issue/623/expose-more-fields-to-... Thanks, Carlos
