Get only the unpublished blogs

When trying to get the unpublished blogs, there is no easy way which i found.

When looking at the script API, I was able to find this

core_v2_blogPost.List({ BlogId: blogIdArg, IncludeUnpublished: includeUnpublishedArg,  });

It has the option to include Unpublished blogs as well, but it will return all published and unpublished. 

Is there an easier way to get just the unpublished blogs?
