How to auto scroll the titanium UI picker?

Since I already facing a time lag for the first time even when I add the options dynamically.

var picker = Ti.UI.createPicker({
  top:50
});
 
var data = [];
data[0]=Ti.UI.createPickerRow({title:'Bananas'});
data[1]=Ti.UI.createPickerRow({title:'Strawberries'});
data[2]=Ti.UI.createPickerRow({title:'Mangos'});
data[3]=Ti.UI.createPickerRow({title:'Grapes'});
data[4]=Ti.UI.createPickerRow({title:'Mangos'});
data[5]=Ti.UI.createPickerRow({title:'Grapes'});
data[6]=Ti.UI.createPickerRow({title:'Mangos'});
data[7]=Ti.UI.createPickerRow({title:'Grapes'});
data[8]=Ti.UI.createPickerRow({title:'Mangos'});
data[9]=Ti.UI.createPickerRow({title:'Grapes'});
data[10]=Ti.UI.createPickerRow({title:'Mangos'});
data[11]=Ti.UI.createPickerRow({title:'Grapes'});
//..........
//..........
picker.add(data);
picker.selectionIndicator = true;
 
win.add(picker);

Is this possible?
