Okay looks like the call dependency resolver does not supports cross-file calls and relies instead on the local repo cloning feature to handle multiple files so the Task.force_store_standalone_script() does not allow for a pipeline defined cross multiple files (now that you think of it it was kinda implied by the name), but what is interesting is that calling an auxiliary function in the SAME file from a component also raise a NameError: <function_name> is not defined , that's kinda sad.
