no way to add prefix to file upload

[matchstick99]

can we add a prefix option to the dreambooth API so that I can upload my ckpt to a custom path on my bucket?
Specifically I want to be able to set the prefix parameter from the following function in rp_upload.py:

def upload_file_to_bucket(
        file_name: str, file_location: str,
        bucket_creds: Optional[dict] = None,
        bucket_name: Optional[str] = None,
        prefix: Optional[str] = None,
        extra_args: Optional[dict] = None
)

However dreambooth worker doesn't use this option at all

        # Upload the checkpoint file
        job_output['train']['checkpoint_url'] = upload_file_to_bucket(
            file_name=f"{job['id']}.ckpt",
            file_location=trained_ckpt,
            bucket_creds=s3_config,
            bucket_name=job['s3Config']['bucketName'],
        )
