I have an art site in which each painting is a pod item. It contains name, image, category, and so on and so forth.

I've created a new category, and need to move a lot of existing artworks into it-- in other words, I need to change the category on quite a few items.

I know I can do this by individually editing each pod item, but this will take a very long time. Is there a good way to bulk edit items? For example, see a list of all artworks in one category, select all or some of them, and give them a new category?

If anyone's aware of input helpers that do this, or even has a pointer on how I should code such a helper, I'd love any advice you can provide. Thanks in advance!
