Bulk export multiple alternate layouts as JPG files to individual subfolders

Hi there,

I'm creating product banners for Amazon. To separate each product set, I am using alternate layouts to be able to export sets of banners to their own subfolders individually. Considering products can number in tens or even hundreds, it takes considerable time to export each alternate layout one-by-one.

I was wondering if there's a script/utility to bulk export alternate layouts to subfolders in JPG/JPEG formats? Or perhaps there's an option like that already in InDesign?

Any and all help is appreciated!
