title: Programmatically change PSMultiValueSpecifier values
body: <p>I have a setting bundle where I'd like to show list of Albums available in the gallery as PSMultiValueSpecifier type. I am done with most of the things with Settings Bundle but the challenge I am facing is updating settings bundle PSMultiValueSpecifier if new albums is added into gallery by user.</p>
  
  <p>Can anyone shed some lights on it?</p>
