laravel的日志系统能不能一个通道可以有几个level等级？

use Illuminate\Support\Facades\Log;
Log::info('发送邮件', $GLOBALS['CFG']);
Log::error('发送邮件', [123]);

我的config/logging.php文件

'default' => env('LOG_CHANNEL', 'stack'),
'channels' => [
        'stack' => [
            'driver' => 'stack',
            'channels' => ['daily', 'single'],
            'ignore_exceptions' => false,
            'level' => 'error,info',
        ],

        'single' => [
            'driver' => 'single',
            'path' => storage_path('logs/laravel.log'),
            'level' => 'error',
        ],

        'daily' => [
            'driver' => 'daily',
            'path' => storage_path('logs/laravel.log'),
            'level' => 'info',
            'days' => 14,
            'permission' => '0666'
        ],

就不知道为什么在laravel-02-01.log文件下就只能看到 error的信息，不能看到info等级的信息？
能不能一个channel可以放两个等级的，如放error和info的信息？
