"Tap-And-Hold" Gesture on ScatterViewItem with Surface Toolkit for Windows 7

I can't find out the best way to im开发者_StackOverflowplement this gesture on ScatterViewItems. Also, I would like to use a wipe-gesture but that's further away ...

There are some support for Gestures in the Blake.NUI project. There's currently only support for Tap and Double tap (see the gesture page) but more could be added. In fact, I'm also in need of a Hold gesture but I haven't finished it yet.
