**Is your feature request related to a problem? Please describe.** The `download_config.json` can be used to upload scores/annotations to slidescore. However, if data is on the HPC without downloading from slidescore, we don't have the file with ID matching. **Describe the solution you'd like** A CLI command to download the url, study id, and filename-id mapping **Describe alternatives you've considered** Downloading again, thus duplicating the slides on HPC.
