Adding Features with no Start on and Due on dates to Starter Roadmap should inherit a Due on date of the Release Date

Currently on the starter roadmap, if you decide to add existing features for an existing release to the view that contain no start on and due on dates, the features are automatically assigned a Start on date of the current date. In most cases, releases are going to be in the future so it would be an enhanced user experience if the Features would automatically inherit the Release Date and then offset the start date by n days (current default to 14). As it is currently, it results in a lot of dragging and dropping and re-sizing to get everything re-aligned as desired in the appropriate timeframe.
