Many to Many with additional field

Hey guys,

i have actual 3 tables:

• customers
• marketingoptions
• customer_marketingoption (pivot with - id | customer_id | marketingoption_id | status | created_at | updated_at)

My Marketingoption-Model

/**
     * Marketingoptions belongsToMany Customers
     * 
     * @return \Illuminate\Database\Eloquent\Relations\BelongsToMany
     */
    public function customers()
    {
        return $this->belongsToMany(Customer::class)->withPivot('status')->withTimestamps();
    }

My Customer-Model

/**
     * Customers belongsToMany Marketingoptions
     * 
     * @return \Illuminate\Database\Eloquent\Relations\BelongsToMany
     */
    public function marketingoptions()
    {
        return $this->belongsToMany(Marketingoption::class)->withPivot('status')->withTimestamps();
    }

My MarketingoptionsController

/**
     * Edit Customer->Marketingoptions
     *
     * @param Customer $customer
     * @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View
     */
    public function edit(Customer $customer)
    {
        $marketingoptions = Marketingoption::pluck('marketingoption', 'id', 'status');

        return view('marketingoptions.edit', compact('customer', 'marketingoptions'));
    }


    /**
     * Update Customer->Marketingoptions
     *
     * @param Request $request
     * @param $id
     * @return \Illuminate\Http\RedirectResponse
     */
    public function update(Request $request, $id)
    {
        $customer = Customer::findOrFail($id);

        $marketingoptionsIds = $request->input('marketingoptions');

        $customer->marketingoptions()->sync($marketingoptionsIds);

        return back();
    }

and last but not least my Form

<div class="form-actions">
    <div class="row">
        <div class="col-md-12">
            <select name="marketingoptions[]" multiple="multiple" id="tags">
                @foreach($marketingoptions as $key => $value)
                    <option value="{{ $key }}">{{ $value }}</option>
                @endforeach
            </select>
        </div>
    </div>
</div>
@foreach($customer->marketingoptions as $option)
    <p>{{ $option->marketingoption }} - {!! $option->value_clear !!}</p>
@endforeach

<!-- Add Article Form Input -->
<div class="form-actions">
    <div class="row">
        <div class="col-md-offset-2 col-md-10">
            <button data-loading-text="Bitte warten..." class="submit-loading-btn btn blue"
                    type="submit">{{ $submitButtonText }}</button>
        </div>
    </div>
</div>

This work all fine now, i can use the multiselect to sync my options with customers in the pivot-table... but i want to switch this select to Radiobuttons grouped by Marketingkoptions to define the status for each option. How can i get the value from the radiobuttons and write it into the pivot (additional) field?

Thanks im realy stuck with that.
