Custom Post types in the Blog Posts content element

It should be some existing questions around this, but I can’t find any answer. How can I make custom post types to appear in the Blog Posts content element? I can’t find any setting around this. We have previously defined three custom post types “News”, “Aptilo in the news” and “Events” without using the actual blog features of Enfold. Now we want to start a blog and use the blog features in Enfold. We have defined a new custom post type called “Blog” and want to show only this post type in the Blog Posts content element. Is this possible?

I can see that this element is pulling ONLY from the standard post type. Strangely enough the custom post type “Blog” appears under the Latest Posts widget to the right.
