OptionPlus and category of product

I bought OptionPlus module and i have a question.
Can I add option to Category? Now i can add option to the product but i want add to category of product.
Thanks

by the way : can you tell me how to add more option to product

You can't add option to category but you can select multiple products and have the current option set copied to them which actually gives you more power instead of just limiting to a single category.

You add more options the same way you added the first one.. click the "Add Option" button
