Copying supplier field values to add. product fields

Here https://fr-auto.1box.link/app/automatization-products/update/edit/ It is necessary to refine the action "Copy the supplier field into the additional product field" https://take.ms/TcFWYG Add the ability to select the supplier number in the order of the product suppliers https://take.ms/5OhG4 Also, it is important that the action copies the value in any case, regardless of the active provider or not, that is, if there is a provider, we copy the value of the field. How many hours do you need to implement?
