Help! How do I make custom option changes to multiple products at once?

[bree_eros]

I need to add a dropdown menu box for shipping options on many products in Magento 1. Is there a way to do make this change for many products at once, so I'm not stuck doing the same thing, hundreds of times? Thanks in advance!
