Hi Peter -

You are right - we don't have a tool like that (we'll look into it).

Near term, one option to minimize artifacts would be to supersample the 
labelmap before transforming it - you should be able to do this with the 
Resample Scalar Volume module and picking a smaller pixel spacing.

HTH,
Steve
