How do I edit categories to send user to specific page?

I am trying to change the direction a particular link goes to. If you go to, you can see in the sidebar under Categories, a page called “Ducati OEM Parts”. How can I change the URL it links to. I want it t link to a different page. Is this possible. Also, I apologize for the site speed in advance. I am trying to figure out how to fix that too.

I'm assuming this is the automatically filled Category block. You would have to replace it with an html block that you would manually fill. All the categories would point to their appropriate dispatch page in the store. This would let you link any item in the list to any destination url. Just remember you would have to add links every time you add a new category.
