Entry for Date through Calendar

Hi Guys,

In my Bex query I have got , two input variables for date. User wants to achieve this through the calendar. But currently in Design studio , we have to enter it manually.  Is it possible in Design Studio 1.5 , to select date from Calendar ?

I have gone through below scn thread , is this functionality part of Design studio 1.6 release , please suggest :
