Incremental/Updates based on OG value while updating ALL documents.

DB["userinfo"]["bankaccounts"]:update({
        method = "equal",
        attribute = "userid",
        values = { 1 }
    }, function(res)
        print(res)
        for i,v in pairs(res) do
            print(v.balance)
            v.balance = v.balance + 1
        end
        return res
    end)```

I'm concerned with how on the backend I'll update the appended changes
I see I have two options after determining which values have been changed.
1. `PATCH /databases/{databaseId}/collections/{collectionId}/documents/{documentId}`
Update each document individually which I'm worried if scaled will affect the rate limit (not only by appwrite but outgoing http limitations)

2. `PATCH /databases/{databaseId}/collections/{collectionId}/documents`
Second case seems more preferable as its all done in one request, however from my knowledge there isn't any way I can accomplish as done in the example, comparing previous data.

Is there a way that I can make method 2 work or do I have to work with method 1?
