Introduce Contributor Role with less rights than Admin/Owner

I would like to expand my company's adoption of FeedBear and increase our user license count, but I cannot do that with the current Owner and Admin roles. I need a "Contributor" role that I can grant to some of my company's users. A Contributor may not: -Administer the project -Administer individual boards -Invite Admin/Contributor users -Change any configurations -Access boards they are not assigned to A Contributor may: -Access only boards they are assigned to -Maintain the status of ideas on boards they are assigned to -Post and Moderate comments on boards they are assigned to Introduction of the Contributor role would allow me to roll FeedBear out to a larger internal audience, additional products, and additional customers. This would likely push us from the Business Tier to the Enterprise Tier (and that's OK)
