Yes, having the exact problem with 3D Coat. Modeling with voxels is very fun but at the end I am left with a model that is almost clean but not up to my standards. Using clay polish, I can clean up the edges but I would prefer to leave ZBrush out of my workflow entirely. I may actually look into the Houdini tool mentioned above as Houdini is one of my main tools. Still, this feature would increase the usefulness of voxel sculpting and would no doubt be useful for others as well.
