Config mail using settings

HI,
is there a way to use https://github.com/codeigniter4/settings to config email instead of  Config/Email
i try to use : 

Code:

      service('settings')->set('Email.protocol', 'smtp');
      service('settings')->set('Email.SMTPHost', 'smtps.xxxxx.it');
      service('settings')->set('Email.SMTPUser', '[email protected]');
      service('settings')->set('Email.SMTPPass', 'xxxxxx');
      service('settings')->set('Email.SMTPPort', '465');
      service('settings')->set('Email.SMTPCrypto', 'ssl');

But if i try to send email i have no smtp configured

You can do it you just need to use an array and then initialize the Email Class.
