Shopify app

We need an application for the Shopify store, which, taking into account the weight and size of the products, could determine in which and in which boxes the order should be packed, then this information is transferred to the warehouse via API and / or order note for packers to see. The boxes have certain sizes, but it must be possible to enter boxes of up to 10 boxes. Where each box has its size in dimensions and the maximum weight that can be placed in it. It must be possible to add up to 20 fields for each product and its variants, where the name, SKU, weight and dimensions can be entered in each field. It must also be possible to impose conditions on each field: 1. Send as is (so don't try to count in a box) 2 Send as is if the only product (so do not try to count in a box if it is the only product in the order, but if there are still products in the order, then the application should calculate or can be put in one of the available boxes, and if not, send product without packaging box) 3. Always send in a box (For the application, the product must be included in the box, if it is the only product, then the smallest box in which, if there are more products in the order, then the application must see which products can still be put together in one of the boxes. The main purpose of the application is to help indicate whether the order products are shipped in a box and in which box (es). As many products as possible should always be placed in one box, taking into account the maximum permissible weight and size of the box and the weight and size of the products.
