Customize Prestashop Advanced Stock Management

Hello, we would need to customize the prestashop's advanced stock management pages. The goal is to make the management easier to the store manager and his assistants, giving them the possibility to perform some bulk operation. In particular we would need: 1. To create a new page based on transferstock layout (see attached files). 2. Add 3 centered buttons in the header: "Add products" "Transfer products" "Remove products". 3. Insert multiple rows to add "Product Reference", "Quantity" and "Price" (when adding). When a row is filled, automatically should appear the next row, with the cursor in the "Product Reference" field. 4. The other select, should be on preconfigured default values. In "Stock Management" we need to: 1. Add "Manufacturers" and "Categories" columns in order to search/filter the product list and remove a couple of not needed columns. 2. Add a checkbox beside every product in order to be able to send selected products to the page above. Note. the image is just an exemple, we may need some adjustment during the project.
