How to allow a call not to be mocked

I want to use Natural mock to mock an object and all the calls to it. But I don't know deterministically if all the calls will be made. So I can't call MockManager.Verify(). BUT, I have other Natural mocks set up in the same test, and these I DO want to use Verify() for.

So is there some way inside of a Natural mock recording to specify "don't fail verification if this call is not made"?
