Umbraco 7 Multinode Treepicker xpath query root node parent of parent

Question

I have Multinode Treepicker in Umbraco 7.4.1. I'm trying to find out how to set the picker to start from the parent of the parent of my current node. I'm also need the option to set the picker to start from the siblings of the parent of my current node.

I tried to use:

$parent/$parent

or

$parent/parent

or

../

no success...

Thanks in advance for all helpers!
