How to use the Arg<> matcher from the Stub() in the Return()?

Question

Here's what i'd like to do :

_service.Stub(s => s.Method(Arg<Dto>.Is.Anything)).Return(new OtherDto { Parent = #My Arg# });

How can i replace #My Arg# with the Arg ? If it is even possible ?

Thanks

Func<Dto, OtherDto> returnOtherDto = dto => new OtherDto { Parent = dto };
_service
    .Stub(s => s.Method(Arg<Dto>.Is.Anything))
    .Do(returnOtherDto);
