Separate Permissions for Approve and Publish in Guide

We really need a mechanism to differentiate publishing permissions vs approving permissions. Our content experts need the ability to approve articles, but not to publish articles. This is because our content experts approve the content of the article, but are not intimately familiar with our publishing requirements and need the extra eyes to help correct spelling/grammar/formatting/etc. 

Unfortunately the way Guide is designed now, it’s an all-or-nothing affair – you either get to approve AND publish, or you do not get either of those abilities. These permissions really need to be separated so we can prevent low quality content from being published before it has been QA'd.
