S3 endpoint customization on Transloadit Credentials

I’m trying to use storj.com as storage with uppy in combination with Transloadit and I want to add s3 credentials since storj provides credentials that are compatible with the s3 sdk; storj docs:Quickstart - AWS SDK and Hosted Gateway MT - Storj DCS Docs. but there’s no area to populate the endpoint URL in transloadit credentials. Is there no way to customize client options like with uppy?

The storage endpoint for S3 compatible storages is not defined in the template credentials, but directly in the parameters for the /s3/store robot using the host parameter: Export files to Amazon S3 | Transloadit Docs
