Showing duplicates in all categories

Is there a way to have an item in multiple categories but hide duplicates of the item from "All The Items" category?

For example

Category: Milk
Category: Yogurt
Category: Stone
Category: Shoes

Item: Cookies (in Milk and Yogurt category)

When I click on All Items I see Cookies twice. Is there a way to show it only once?

Dear

In this version, component does not support multi categories for one item. We'll consider if it can be added in our future release version of the extension. If you want, we can customize this feature for you with an extra fee. Or I will find the solution and we can discuss about it so you can modify the source code by yourself
