How to implement supplier item relationship P43090 for certified suppliers

We are looking into start using the certified suppliers function in P43090 supplier/items relationship.  The function tested out ok so we can block certain items from each supplier but using the "not certified" UDC code, our main issue is we can't setup the logic that unless its's certified the items can't be ordered.

According to Oracle, you need to add every items / supplier combination in order to block these orders.  Howevere, one of the requriement is to stop user from ordering the parts from the wrong supplier - which we don't know what that supplier/part is ahead of time.  We also looked at the item restriction (I/E) from supplier master but it has similar limitation.
