ListPicker - how to make current selection show when full page view opens

Question

I'm using the ListPicker from the latest Silverlight Toolkit on Mango

I've got a long list (100 items) of simple text items to choose between - using single item selection mode.

When I click on the ListPicker it opens up in full screen very nicely, but it doesn't scroll to the current selection.

This is a pain for the user - who typically wants to move from "item75" to "item76"

I've looked through the available properties, events and source code, but I can't see any obvious way to get the list to scroll the current selected item into list when the full screen mode opens.

Anyone got any ideas?
