Flamenco custom file naming

I’m trying to change the code in the default basic script in Flamenco. Currently it saves the files with a basic numbering scheme… ‘#########’ i’m trying to concatenate the job name with the sequential numbers and it’s not working. I want to do something like jobname + ‘#######’

THE ORIGINAL
eval: “str(Path(abspath(settings.render_output_root), last_n_dir_parts(settings.add_path_components), jobname, ‘{timestamp}’, ‘######’))”,
