Searching Arena with Birth Year - Bug or 'Feature'?

Somewhere in the long line of arena updated versions, we lost a useful feature. You can no longer search for a birthday complete with year in the White Pages module. If you type a year, when you leave the cell to click 'Go', the cell reformats your search term and drops the year. We love the ability to search by the generic month and day, but not at the expense of not being allowed to ever include the year. Can the module be made smart enough to discern the difference? Would that be a setting on the module settings that could be toggled on/off?
