Use the “include command :” directive. You will probably need to run an in-line or external shell script to echo a submit key-value pair, such as:
DynamicFilename = my_input.txt
Ideally the command should put a double dash as the last line of its output, since that signals the end of the values. That’s then available as $(DynamicFilename) in the rest of the submission.
