I am creating a website for somebody, there are many categories and sub categories within the website. When creating a post and selecting the categories it displays the categories and sub categories but when I go to edit the post the checked boxes are all displayed at the top and it makes it very hard to see what sub category is a sub-category. I want to change the way it is displayed to the admin so that instead of the checked boxes being displayed at the top and losing the structure. I want it to display the checked boxes with the structure referring to the categories and sub-categories.
Here are screen shots to help explain.

Any help would be greatly appreciated thank you.
