If I understand what you mean by "hash of a hash", I believe not.
As I posted yesterday:
Beware the pitfall. If:
W = 'a.b'
X = 'c'
Y = 'a'
Z = 'b.c'
then Stem.W.X and Stem.Y.Z refer to the same member of the
compound, regardless that none of the subscripts are equal.
Multiple subscripts are flattened, in a possibly degenerate manner.
