Rackspace Cloud Files(CDN) – Using Multiple Containers

I’ve recently set up the plugin with success, however I recently came across this article: http://www.rackspace.com/knowledge_center/article/best-practices-for-using-cloud-files It recommends using multiple containers for serving different file types for speed optimization and organization.

How can I implement this when there is only one container field in the CDN settings for rackspace?

Thanks in advance

Mike
