Allow users to change quantity for order bumps at the checkout

Hello!

Recently we were using the free version of WooCommerce Checkout Upsell Funnel.
We needed a functionality where users can change quantity for order bumps. After seeing that the product quantity feature was locked we purchased the premium version.

However, this feature only allows to change quantity in the backend.

Is there a way to allow users to change quantity in the front end? Please see – https://prnt.sc/juNrP3vd2sB7
There is such functionality for CartFlows, however, it seems that it is not compatible with this plugin because when AJAX is initiated by CartFlows the Upsell products carousel does not load. Please see – https://www.loom.com/share/699a4dd8bd974b4395047c4cca526aa3?sid=fe6bca01-a6fc-4fff-8b07-33ffa4376219

Do you have any suggestions? If needed we can pay for custom work.

Please let me know.

Thanks!

Rudolfs
