   Is it possible to create a multi dimensional associative array

import std.stdio;

    aa["Pool"] = [1: "Development", 2:"Quality"];
    foreach(i; aa["Pool"].byValue) { writeln(i); }

No. ndslice provides rectangular arrays. An associative array (as 
it defined in D) can't be really 2D, instead, it is an AA of AAs 
like in your example. A real 2D analog associative arrays are 
DataFrames. It is a postponed WIP ndslice feature.
