How do I defer custom field dependencies for actions?

[jdion84]

Right now I have a custom field called DealerOptions:

class DealerOptions extends Field
{
    public $component = 'dealer-options';

    public function dealers($dealers)
    {
        return $this->withMeta([
            'dealers' => $dealers,
        ]);
    }
}

there is a dealers method which passes data to the Vue component

i am using a service provider to register a singleton for these options:

        $this->app->singleton('dealersWithAssigns', function (Application $app) {
            return Dealer::query()
                ->withCount('assigns', 'assignsToday')
                ->orderBy('name')
                ->get();
        });

i use this singleton when registering the dealer options in the field

i use this in an action, here are the action fields:

    public function fields(NovaRequest $request)
    {
        return [
            DealerOptions::make('Dealer Options')
                ->dealers(app('dealersWithAssigns'))
                ->onlyOnForms(),
        ];
    }

the reason i am doing it this way is because if i don't use a singleton, it will run the query for every single model when viewing the resource and causes the page to load extremely slowly

is there a way to defer resolving of the dealers until the action modal actually pops up?
