How to prevent an element from being selected twice?

I am using a repeater to manage a pivot table like this: I don't want users to be able to attach the same affiliate twice 
Repeater::make('campaignAffiliates')
                                    ->schema([
                                        Forms\Components\Select::make("affiliate_id")->relationship('affiliate', 'company_name')->required()->columnSpanFull(),
                                        Forms\Components\ToggleButtons::make('cap_type')->inline()
                                            ->live()->default('unlimited')
                                            ->options(['unlimited'=> 'Unlimited', 'daily'=>'Daily', 'weekly'=>'Weekly'])
                                            ->colors(['unlimited'=>'success', 'daily'=> 'warning', 'weekly'=>'primary']),
                                        Forms\Components\TextInput::make('cap')->hidden(fn ($get) => $get("cap_type") == "unlimited")->numeric()

                                    ])->columns(2)
                                    ->relationship(),
Repeater::make('campaignAffiliates')
                                    ->schema([
                                        Forms\Components\Select::make("affiliate_id")->relationship('affiliate', 'company_name')->required()->columnSpanFull(),
                                        Forms\Components\ToggleButtons::make('cap_type')->inline()
                                            ->live()->default('unlimited')
                                            ->options(['unlimited'=> 'Unlimited', 'daily'=>'Daily', 'weekly'=>'Weekly'])
                                            ->colors(['unlimited'=>'success', 'daily'=> 'warning', 'weekly'=>'primary']),
                                        Forms\Components\TextInput::make('cap')->hidden(fn ($get) => $get("cap_type") == "unlimited")->numeric()

                                    ])->columns(2)
                                    ->relationship(),
