The blog page, if set in the settings >> reading >> posts page looks like the following. Besides, the option to edit it with Cornerstone is disabled.

If the blog page is unset in settings >> reading >> posts page then it looks like below, means, the featured page is showing up and the page title is also shown. Of course, the blog posts are not listed. The option to edit the page with Cornerstone is enabled.

How can I assign the blog page as default post page and keep the layout unchanged (featured image and page title showing up)? It would be also good to keep the possibility to edit the page with Cornerstone.
