Can I pass in a filament resource's form into createOptionsForm()?

For example we have Post belongsToMany Tag and I want to be able to create new tags on-the-fly when selecting tags for a Post.

class TagResource extends Resource
{
    public static function form(Form $form): Form
    {
        return $form
            ->schema([
                Forms\Components\TextInput::make('name')
                    ->live(debounce: '1000')
                    ->afterStateUpdated(fn (Set $set, ?string $state) => $set('slug', Str::slug($state)))
                    ->required()
                    ->unique()
                    ->maxLength(50),
                Forms\Components\TextInput::make('slug')
                    ->required()
                    ->unique()
                    ->maxLength(50),
            ]);
    }

class TagResource extends Resource
{
    public static function form(Form $form): Form
    {
        return $form
            ->schema([
                Forms\Components\TextInput::make('name')
                    ->live(debounce: '1000')
                    ->afterStateUpdated(fn (Set $set, ?string $state) => $set('slug', Str::slug($state)))
                    ->required()
                    ->unique()
                    ->maxLength(50),
                Forms\Components\TextInput::make('slug')
                    ->required()
                    ->unique()
                    ->maxLength(50),
            ]);
    }

class PostResource extends Resource
{
    public static function form(Form $form): Form
    {
        return $form
            ->schema([
                Select::make('tags')
                    ->multiple()
                    ->relationship(titleAttribute: 'name')
                    ->createOptionForm([]) // what is a DRY solution to avoid copy-pasting the form fields?

class PostResource extends Resource
{
    public static function form(Form $form): Form
    {
        return $form
            ->schema([
                Select::make('tags')
                    ->multiple()
                    ->relationship(titleAttribute: 'name')
                    ->createOptionForm([]) // what is a DRY solution to avoid copy-pasting the form fields?

Forms\Components\Select::make('region_id') ->relationship('region', 'name') ->label('Region') ->required() ->createOptionForm(fn(Form $form) => RegionResource::form($form)) ->searchable()->preload(), Formatting on mobile sucks sorry!

Yes, that did the trick! Nice and easy. Thank you. Here's the updated code:

Select::make('tags')
    ->multiple()
    ->relationship(titleAttribute: 'name')
    ->createOptionForm(fn(Form $form) => TagResource::form($form)),

Select::make('tags')
    ->multiple()
    ->relationship(titleAttribute: 'name')
    ->createOptionForm(fn(Form $form) => TagResource::form($form)),
