Bulk Import

Hello,

Thanks for getting in touch with us.

As per your requirement, we need to do customization in our plugin.
Here we have pro version of this plugin is available,
Demo of pro version of product attachment plugin: http://wooproductattachment.demo.store.multidots.com/
Which has the functionality like you can attach any attachment category wise, where the attachment would be added to that product which category is assigned. For more clarification please refer the doc of pro plugin: https://store.multidots.com/docs/plugins/woocommerce-product-attachment/bulk-products-attachments/

But if you want the different attachment to each product then as of now you need to attach your attachment manually.

Let us know your feedback.

Thank you,
Multidots
