[Plugin: eShop] Mass edit ET Settings field

Hello, I am working on a project to implement a blog into eShop with eStore theme. I’ve got it mostly working and have made a drop down menu in the ET Settings section of the post page to switch between product pages and blog posts, however I have imported 200+ blog posts that are all product pages and I was wondering if there was a way to mass edit that field instead of going at it one by one.

Thanks.
