I'm sure this is easy and discussed elsewhere, but I have products which are linked to two different categories. Is there a way to disable one of the categories without automatically making the products in that category disabled?

For example, I may have 100 products that are listed in my store, but also linked to a "Christmas Magic" category. If I want to disable the Christmas Magic category so that it doesn't show up on my menu list, I don't want all items within there to be disabled throughout the rest of my store, know what I mean?

Is there a mod or something which allows you to easily unlink multiple items from a category, or at least disable the category while leaving the items enabled on your site?
