Add keywords to products?

Hi,

I've been adding custom keywords to my products, but I want to add standard keywords to all products.

I know I can do this as a mass action, but it seems like it would replace the keywords that are already there. How do I keep the custom part that's already there, and then ADD the keywords I want to the end?

Thanks

Hi,

You can do it with a mass action.
You can use the action "update the values" on the column product_keywords, but instead of selecting "string" and entering the text you want for all the products to replace what is already there, you can select "operation" and enter something like that:
concat(product.product_description,',extrakeyword1,extrakeyword2')
