Hello, I am trying to construct an AssetArchive from a folder and upload it to an S3 BucketObject. It works fine, but it creates the archive in ZIP format regardless of what extension and content-type I use on the S3 object. I need the archive to preserve file permissions (e.g., executable bit), so I want to use tar.gz format. I can't find an option anywhere in the documentation for setting the archive format. Any ideas?
