Hi Abraham Tol,
Correct me if I'm wrong here, do you want to as we filter a category (eg: news) the calendar view it will only shows the post that belong to the category(news category)? Unfortunately, it is not possible currently.
By the way, if this a priority, please do post them on our sales section at
https://crm.stackideas.com and our sales department would get back to you with a proper quote.
