AWS Signature V4 Default Breaks EMC ECS Connectivity

Hello, I downloaded the latest version of Cyberduck but had to fall back to v 5.0.11 the new feature you added called "[Feature] Default to signature version AWS4 when connecting to third party S3 providers" is breaking S3 authentication to EMC's 3rd party S3 storage arrays - ECS.

The error returned is shown in the attached screenshot.

Can you please create a UI element that lets me specify the S3 signature version on a per-bookmark basis? I couldn't find out how to switch this in the options so I had to uninstall the new version of the software and go back to using an older version.
