How to add a tip to *an existing/validated* item

[0xAskar]

I was wondering how can you add another consideration for tipping for already validated/existing items on Opensea?
It says on the documentation that

As all consideration items are supplied at the time of order creation, dynamic adjustment of recipients or amounts after creation (e.g. modifications to royalty payout info) is not supported. However, a zone can enforce that a given restricted order contains new dynamically computed consideration items by deriving them and either supplying them manually or ensuring that they are present via isValidZoneIncludingExtraData since consideration items can be extended arbitrarily, with the important caveat that no more than the original offer item amounts can be spent.

However, I'm confused as to what it means that the zone can enforce a given order receives new dynamically computed consideration orders. If there are any examples or suggestions on how to do this for existing / validated items on Opensea, that would be great. Thanks!

Okay, I think I was able to get it figured out with some help. When adding a tip, it makes sense to add the tip to the fulfillOrder instead of the considerations. This format (public async fulfillOrder) can be found in the seaport.ts github page. The format can be found in the types.ts github page.. Should be comprised as the following format.

The Seaport documentation has no mention of tips in the fulfillOrder at least from my extensive search, only the discussion of in the consideration in which it said it wouldn't work well, so I think it would be great if the documentation was updated with my thorough analysis explanations for tips.

{ itemType: 0;
    token: string;
    identifier: string;
    amount: string;
    endAmount?: string;
    recipient: string}

public async fulfillOrder({
    order,
    unitsToFill,
    offerCriteria = [],
    considerationCriteria = [],
    tips = [],
    extraData = "0x",
    accountAddress,
    conduitKey = this.defaultConduitKey,
    recipientAddress = ethers.constants.AddressZero,
  }: {
    order: OrderWithCounter;
    unitsToFill?: BigNumberish;
    offerCriteria?: InputCriteria[];
    considerationCriteria?: InputCriteria[];
    tips?: TipInputItem[];
    extraData?: string;
    accountAddress?: string;
    conduitKey?: string;
    recipientAddress?: string;
  }):
