Get parents of currently selected item

[seanferns]

I am trying to use the nested search to get all immediate parents of the currently selected item.
The hierarchy is:
test1

parent1

parent2

test2

parent1

parent2

parent1

child1

child2

parent2

child3

child4

The first saved search is "limit search to selected...." with "parent count" greater than 1.
The next search is Item is "parent of" the search above without the "limit search to selected...." selected. Now click on Parent1 and this search. This returns all items which have linked items.

Is there a way I can get the search to return only test1 and test2 ?

Sample of the above is attached.

As an aside from this, 2 enhancements which would be very useful are
a) getting the current item id and
b) allowing direct SQL queries which return one or more itemIds
