NullSubstitute with dynamic value

[dnperfors]

Given the following types:

public record Source
{
    public DateTime? Date { get; init; }
}

public record Destination
{
    public DateTime Date { get; init; }
}

When I map from Source to Destination, I want to substitute the null value for Date to DateTime.Today, however it looks like that the NullSubstitute expects a fixed value. Would it be possible to get an overload of NullSubstitute that accepts a Func<object>?

You can easily use a resolver or a value converter for that.
