WordPress Bulk Attribute Edit Plugin

I need a custom plugin added to my WordPress / WooCommerce admin that lets me bulk-edit product attributes from a single table instead of opening every product page. From the dashboard I’ll choose the products—by category, brand, or a quick search—then the plugin should build a spreadsheet-style grid with one row per product.

A “+” control will allow me to insert as many attribute columns as I want; in day-to-day use that’s usually Color and Size, though the list must pull from all existing global attributes so I can add others whenever needed. Each cell shows a dropdown populated with the valid terms for that attribute, making updates fast and error-free. When I hit Save, all selected simple products update in batches so the site never lags.

Please code it so it respects existing attributes and Linked Variations, and give me a small test run on a handful of products before I roll it out to the entire catalogue.
