I want to add an additional function like category addition while new post so that while publishing new post i can select both category and my additional box option also.
Like i am selecting category only i get this URL:
sitename.com/category/business - it will display my all posts in this category
and simultaneously i need the same post in other category box whose URL will be like this:
Please don't suggest to select multiple category from single category box, i need different custom URLs
