Dear Galaxy Team,

I started using Galaxy few months ago. I'm now setting up my first "real" workflows.
I would like to keep the name of my input file through the various steps as dataset's label, maybe also modify it a bit, and finally give a "proper" name to the result file downloaded.

A simple example:
1) date-sample_name.gff3 --[step1]-> date-sample_name-step1.tsv
2) date-sample_name-step1.tsv --[step2]-> date-sample_name-step1-step2.txt
3 download date-sample_name-step1-step2.txt

I've seen that I can use the 'label' attribute in the tool config "data" tag to do so. But I don't know how to access the ${input.label} (?) and how to modify it.

I doesn't stop me using my workflows, but it would definitely help my users not to get lost when they use them.

Best regards,
Tanguy Le Carrour
