As you know, s.d. requires a global value (mean). It is possible to iterate
in DX over a set of values using Get/Set pairs (best done in a macro using
GetLocal/SetLocal). But, this is very inefficient and painfully slow if you
need to do more than a few iterations, or if you expect real-time sorts of
responses.

Better to precalculate this info and import s.d. as a separate component
mapped to the same positions as the vectors are.
