Manually split order with multiple addresses

Hi all,

In my shop I have a functionality that allows customers to set multiple shipping addresses in 1 order. When customers use this, I want to be able to manually split the order into multiple orders, 1 for each shipping address. I installed this app and tried to do so, but nothing happened and the order wasn’t split up.

For info:

I use this app for the multiple shipping addresses: https://woocommerce.com/products/shipping-multiple-addresses/

I only sell 1 product, so the split should be based on the quantity of that one product (e.g. someone places an order for my product with a quantity of 5, and thus with 5 addresses. Then the order should be split into 5 orders).

Hope anyone can help me out here!
