Need a permissions ability between Reviewer and Contributor for features description editing

Problem Statement: The current permissions/licensing structure of Aha is cost prohibitive for companies with larger business review teams who need update feature descriptions prior to development (i.e. moving features through stage-gate prior to approval and development). As such, the only way to manage these updates is to put this on the shoulders of a Contributor or Product Manager; this is time consuming and overtasking IMHO because in many cases (like ours) the people in these roles have additional responsibilities.

Note: This this update/edit feature descriptions ability information beyond the existing reviewer commenting functionality. Today, only the contributor or PM roles can edit/update feature descriptions.

Potential Fixes

1. Create a new role that would have have the ability to update feature descriptions (not not manage other aspects such as release, tags, etc.), or 
2. Update the Reviewer Role (Reviewer Plus) with a permission flag/toggle that would allow the PM to toggle a Reviewer description updating permission; include an option to implement this globally (product) or per user; the latter would be better because I wouldn't' want to give all my Reviewers this ability.

Note: This role/ability, IMHO, should not have the ability to manage the feature itself (e.g. change other options such as its release, tags, initiatives, etc.; or perhaps a very limited set of choices.) That kind of management is suited to the Contributor role.

Business Benefit

• Greater collaboration with our business units who provide a template of feature description text for each feature.
• It makes Aha! that much more an awesome tool because it offers more flexibilty.
• We're building our roadmaps and I have too many people contributing pieces. They should be able to work within their business units and update feature descriptions on their own.
• Will make me stop looking at alternative software or painful workarounds.
