Fixing this would be a tad messy, because the information is not
propagated up through a utility-statement Portal. I guess I would ask
why you're using EXECUTE at all; it's considerably less efficient than
invoking the prepared statement via the protocol-level operation for
doing so (Bind, then Execute).
