Best way to override Delegate creation while keeping all other customizations

We often use factory methods (Func<T>) in classes. This works well in conjunction with AutoFixture. The only problem I have is that the generated code always returns the same value.

Let´s take a sample class:

public class Sample 
{
  private readonly Func<IFoo> _createFoo;

  public Sample(Func<IFoo> createFoo)
  {
    _createFoo = createFoo;
  }
}

So if I would have to write the code AutoFixture does automatically it would look like this:

var fixture = CreateFixture();
var foo = fixture.Create<IFoo>();
var sample = new Sample(() => foo);

I am of course simplifying what AutoFixture does, but the result is that I will always get the same instance whenever I call the factory method. Can someone please direct me into customizing this behavior so that the result is like this:

var fixture = CreateFixture();
var sample = new Sample(() => fixture.Create<IFoo>());

Should we tag this issue so that if a new major version was to come, we could take the chance to introduce this breaking change?

Yes I would love to see this changed in the future, but as said, there might be someone out there relying on this behavior.
