如何在magento中为1种类别创建相同的产品自定义选项？

I have 5 or more products and each product have same 20 product options, In product options we have 6 drop down and each drop down have more than 300 values.

In future we will add this type of product also.

It is possible to create product options one time only & add those options in all product whatever we want?

Thanks
