I had the same problem when I started to work with Galaxy workflows.
My workaround is:
1) Modify the first tool of the workflow
Make it work on a simple text file that contains a list of input file
paths (one by line) instead of several files.
2) Create a galaxy tools that can create this list from a galaxy history
3) Build a workflow with only one input slot for the first tool (the list)
Hope this helps :)
Have a nice day,

Thanks for the reply.
However, my question was not about building tools.
My question was about building a workflow (using the workflow editor
with existing tools), as a user of galaxy.
Using the workflow editor, when I create a workflow using a tool that
allows a variable number of inputs, it seems that I have to define the
number of inputs during workflow creation and not when I run the
I was just asking if it would be feasible to have a variable number of
inputs (only defined when a running instance of a workflow is created).
It feels to me that the answer is no.
