Info Section Bulk Manager replaces one info section with another on every product that has it, in a single run. Choose the section to take off and the one to put on, and the app finds the products that carry the first one. Every run goes into an undo log in your site's CMS.
The built-in product page can already add and remove info sections on products you pick by hand. This app adds three things: choosing products by the sections they already have (or by name or collection), more than 100 products in one run, and undo for any run in the history. Undo puts back only what that run changed, so later manual edits stay.
Before anything is written, a preview shows each product with the sections coming off in red and going on in green. Products edited elsewhere after the preview are skipped, not overwritten. Sections themselves are never deleted, and names, prices, stock and images are not touched.
The app is for stores on the new product catalog (Catalog V3). Stores on the older catalog see a notice in the app, and nothing is changed. The free plan changes up to 20 products per month, and Pro removes that limit. Preview, history and undo are on every plan.
