Assigning A Feature To All Products

When you got many features editing in bulk is not easy, even browser breads.. Is there an easy solution to assign same new feature for example "new feature" "Good" to every single product fast and painless?

Import. But if you have more than one feature, you will need to import them all together.

~300 products needs to be updated, somehow I never succeeded with correct import..

I agree with The Tool, the only way to do it without additional modifications - Import

When I got many of them it is really not so nice looking on cvs editor..
