I have several products, these products are repeated in almost everything but they have an identifier that comes in a packing list that they send me and I automatically upload it to Odoo, it has Lot and PO, I enter the white shirt into the inventory as a product, but it goes to come out in different processes, colors, how can I create a field so that the user in the end knows that this shirt is for that color that comes directly on the packing list and not take another one from inventory that has the same characteristics but different PO and Color example

White Short Sleeve Shirt PO 11458 QTY 512 assigned color Shadow, this is how it comes on the packing list, but I will enter it as a white shirt only, then I will assign the production order for the color that it is, but the shirts are already established, how do I do so that when the production order is placed, I only grab the pieces that are already assigned, so to speak, it is 1:1 that is already established and cannot take pieces that exist in the inventory.

The packing list comes with several products and there are many different quantities of product, I need everything to be more efficient and take less time when performing functions, but I want everything to work correctly, how can I do it?
