Portfolio Roadmap-Add option of Release Month and Date Merged

Why is it Useful - Current view is displaying year/quarter and months in swim lanes, adding month/date will help to view the release months more explicitly
Who would benefit from it - The portfolio manager and release manger will get benefited.
How should it work - In the filter option at Portfolio Roadmap page it is showing 1Qtr, 2Qtrs, 1 year and 2 years, just we need to add Month also.
