Option to refresh CDN cache for users

When updating a file in the CMS editor with the same name,this will not show as updated on the live version of the site until the CDN cache is refreshed. It can be concerning to a customer if they edit something in the CMS and don't see it on their live site. It would be nice if we could offer an option to users to clear this cache so that they can get the site updated throughout the entire network when they are making changes.
