I am using expressions such as: {File.Categories|filter:Subject;level:3}, for instance in the category A|B|C|D this would give C
Could an element be designated counting from the bottom by using a negative index; that is {File.Categories|filter:Subject;level:-2}, again to give C?
It would be useful, where the number of elements vary under a common top node, so that, for instance, the one second from bottom could be selected, irrespective of the number of nodes in the category. So with expression {File.Categories|filter:Subject;level:-2}: for Subject|B|C, 'B' would be selected and for Subject|D|E|F, 'E' would be selected.
Added for the build 5.0.138. I was working on variables today and this one was not hard to do.
