Relationship with pivot

I have the following problem. I have two models, Winery and Exhibition with a many-to-many relationship. The relationship has an added pivot attribute: public function exhibitions(): BelongsToMany { return $this->belongsToMany(Exhibition::class)->withPivot('with_masterclass'); } in my winery resource I have a SELECT where I choose the Exhibition: Forms\Components\Select::make('exhibitions') ->relationship('exhibitions', 'country') ->options(Exhibition::where('active', '=', 1)->get()->pluck('name', 'id')) ->native(false) ->preload() ->multiple(), And this is working. I select the exhibitions and when I save larevel/filament is populating the exhibition_winery table. The problem is that I would like another SELECT, identical to the previous one where I can choose the masterclasses and this should set to True the pivot field 'with_masterclass'. From the UI point of view you can see in the attached image what I would like to achieve. Thank you!
