Our org is considering using our internal Idea Manager to track market unit feedback/issues; this would allow a mechanism to "pre-screen" feedback before formally entering features into production Rally. As our Rally Admin, I am researching for the market units. Is there a way in the Idea Manager to add custom fields? I couldn't quickly see that in the admin area. If yes, is it a correct assumption that all fields that are mandatory in production Rally, would have to be mandatory in the Idea Manager, in order to facilitate eventual mapping and passthrough of data?
