Performance Issue Between Two Date Slicers

Hi,

I have two slicers: Year and Date. I noticed there is a performance issue during picking of a year and changing the date range. 

Before I selected any specific year/date, the Year Refiner was initially set to All Years and Date Refiner selected dates between 1/1/2010-1/1/2013 (all dates in the calendar table). At first, I selected the year 2011 and moved the dates to be 10/6/2011 to 12/31/2011:

If I wanted to see data on the same date range but different year, I would change the year to be 2010. At this point, the date refiner may stay the same or position itself at the start date found in the previous input. My expectation would have been to see the dates in the refiner stay the same MM/DD but change in YEAR to 2010.

Is there any way to improve this issue? Thanks for any help!
