Use value from parent model as default in attachAction relationmanager

I have a Service Model and a Doctor Model, and a ServiceDoctor Pivot Table.

I am using a relation manager to attach Doctors to Services. The Pivot Table also has some extra fields like price and time. The service table also have fields named default_price and default_time

I want to attach action to set the default values during attachment. Is this possible?

class DoctorRelationManager extends RelationManager
{
    protected static string $relationship = 'doctors';

    public function form(Form $form): Form
    {
        return $form
            ->schema([
                Forms\Components\TextInput::make('first_name')
                    ->required()
                    ->maxLength(255),
            ]);
    }

    public function table(Table $table): Table
    {
        return $table
            ->recordTitleAttribute('first_name')
            ->columns([
                Tables\Columns\TextColumn::make('first_name'),
                Tables\Columns\TextColumn::make('price'),
                Tables\Columns\TextColumn::make('price_online'),
                Tables\Columns\TextColumn::make('time'),
            ])
            ->filters([
                //
            ])
            ->headerActions([
                Tables\Actions\AttachAction::make()
                    ->preloadRecordSelect()
                    ->form(fn (Tables\Actions\AttachAction $action): array => [
                        $action->getRecordSelect(),
                        Forms\Components\TextInput::make('price')
                            ->numeric()
                            ->required()
                            ->label("Price Offline (0 if not provided)")
                            ->default(function () use ($action) {
                                return $action->parent?->default_price; // I want the default_price to be pulled from the parent Service class
                            }),
                        ...
                    ]),
            ])
            ->actions([
                Tables\Actions\DetachAction::make(),
            ]);
    }
}
Solution
Figured it out, i had to use
->default($this->getOwnerRecord()->default_price),
