To clarify, I want to specify the default selected file name for an Input Dataset block in the workflow, but I'd like to keep the option open to select other input names with the same type. When I specify a file type for a tool's input, it is not enough. The input dataset can end up finding dozens of files that are txt for example. I want to know all possible tool_state annotations for Input Dataset (tool_id: null). Where would I find this?

My goal is to specify the default input file names for a number of tools in a workflow. Is this possible, or am I limited to only providing the file type or extension? If possible, can you provide an example?
