How to enable reordering in OutlineGroup

Is it posible to enable reordering of elements in an OutlineGroup?
I'm looking for something like ForEach.onMove(perform:) that works with a tree like structure.
Same thing here
It'd also be nice to have onInsert for dropping foreign elements into the tree.
Need this as well.
