Do not show certain categories of products

Hi!

I use your “carousel Slider” plugin and I love it!

But I would like to show the products of all categories except those of two or three of them.

It’s possible?

That works just like “Product Categories” but that the categories that are added are those that are not shown, that is: just the opposite of how it works now …

Thanks for your plugin and your time.
