customer consignment stock but at a supplier level instead

We've a situation where we want to have raw material at a supplier and also keep track of this. Its sort of a customer consignment stock but at a supplier level instead. In example we want them to keep steel raw material at their site (to guarantee deliveries and because this raw material is quite costly right now)  and when we buy a finished steel products from them the consignment stock would have to be adjusted accordingly. Is there are solution for this in IFS today? If yes, can you guide me in the right direction I 'vent been able to find anything in the online documentation.
