Enable A/B testing in workflow/automated emails

Would be great to see a feature that enables metric setting for A/B testing automated emails in workflows. I know that my email opens are doing well for an email type but for example what if I would like to A/B test the CTA in my email. Would be great to have this feature. Also would be nice to see both emails from within the workflow. I wasn’t sure mine was working at first because I only see version A represented in the workflow.
