randomize and $dist_normal?

Is there a way to make the randomization of variables via randomize() use one of the different RNGs listed in 20.15 of the IEEE Std 1800 (such as $dist_normal or others)?  Or does the use of one of the alternative RNGs require manually doing randomization via direct calls to those utility functions ($dist_normal, etc) in the post_ or pre_randomize() functions?
