News post with Template

Hi community!

I am buildning a 'blog' with the News webpart.

At the moment I have built a template with some text and images web parts and thats all fine.

BUT - when I am trying to write a new 'blog'/news post using the template I can not add or remove web parts or even change images in the web part etc.

Is that by design?

I wish to add these web parts like "dummys" for editors to remove or use if they want.
