Can I include other children in blog?

I’m using antimatter, and my home page is ‘News’, but I also have a section named ‘Blog’. Id like see both News and Blog inserted into the home page. I tried to add @self.items, @blog.items to the blog items field but it renders no data once its saved. Anyone know how I can do this?

Are you asking for a way to show a particular post in both News and Blog? I want to know of a way to do the same,

Aand a way to edit the sidebar. I simply can not edit the sidebar or control the contents of the sidebar whatsoever
