Any Global method to add Accessories?

I love how you can add options globally, but as I am transferring a site to CS-Cart 3.01 Pro I have hundreds of products to add accessories to and it's very slow to do it one at a time.

Yes, you can set one up and clone it, but I have 950 exsisting products to work with. I'd like a way to set them up globally or copy from one to many products.

Same question with buy it together?

Any ideas?
