Viewing and changing category assignments in large numbers

We have a shop installation which is nearing completion containing around 900 products across multiple categories (most products appear in several categories). A number of products are miscategorised and we are looking for efficient ways to address this.

Is there a feature in the HikaShop back-end which will allow us to list all products for a particular category, and have the option on that screen to remove the selected items from the category, but NOT a sub category? We wish to retain the products in other categories, but amend the category contents category by category.

Thanks in advance.
