Highpoly Relax Brush

I love sculpting in blender but at the moment i am trying to sculpting in zbrush then now i want back sculpting in blender i feel blender a bit harder especially while smoothing/relaxing highpoly mesh, i try use relax with slide relax brush but it doesn't affect on highpoly mesh, so.. maybe blender will have relax brush for highpoly in the future?
