Laravel Cashier + Can you customize the additonal field for a subscription

I have a question while using laravel cashier with stripe, can you customize stripes additional fields to a field that is not supplied by stripe. Like if i wanted to customize stripe table and add my own field is that possible?

Just to test i added a integer field called random_id to the stripe subscription migration, when trying to make a subscription i set the default value to 1 i just to see if it would display in the database and it doesn't so i am wondering how can i achieve this using laravel cashier.

paymentcontroller

   public function subscribe(Request $request)
    {
        $user = auth()->user();
        $paymentMethod = $request->payment_method;

        $planId = $request->plan;
        $user->newSubscription('main', $planId)->create($paymentMethod, [
            'random_id' => 1,
        ]);

        return response([
            'success_url' => redirect()->intended('/')->getTargetUrl(),
            'message' => 'success'
        ]);
    }

Payment.blade.php

@section('content')


   <select name="plan" class="form-control" id="subscription-plan">
                            @foreach($plans as $key=>$plan)
                                <option value="{{$key}}">{{$plan}}</option>
                            @endforeach
                        </select>

                    <input placeholder="Card Holder" class="form-control" id="card-holder-name" type="text">

                    <!-- Stripe Elements Placeholder -->
                    <div id="card-element"></div>

                    <button class="mt-2 btn btn-sm btn-primary" id="card-button" data-secret="{{ $intent->client_secret }}">
                        Subscribe
                    </button>
