Third Party Vendor Fulfillment Service

Hi, I would like to offer fulfillment services only for sellers who decide to outsource logistics for one or more products.
In practice, the sellers send the products that they want to outsource the logistics to the general warehouse of the marketplace and the marketplace manages all the logistics from a single warehouse and obviously incorporate orders from multiple suppliers that use the marketplace logistics.
For each product it would be necessary to add a check to understand if the product is in the logistics warehouse and a field to add the position on the shelf.
