Picker is too slow, why does Xamarin set SelectedIndex each time item added? *Performance Tested*

So the picker is extremely slow. Ive attached a screen shot. So in one view of ours it took 22sto load. I removed the .Add of items to the pickers and our load when down to 3.6s per the profiler. Why is it calling SelectedIndex on every add? Can we PLEASE open up the Items property so we can set the entire collection at once?

Any info about the picker would be greatly appreciated!

Thanks
