Option to show only primary study in left side Studies List by default

Greetings,
Im using the latest version of OHIF viewer ie 3.9.1 and was wondering if there is an option to show only primary study in left side Studies list by default. Currently by default it shows all of the patients studies by default.

anyone? There is no way to achieve this via the config file?

This is fixed in release/3.9 branch and master, now you can defined a customization to be primary, add this to your mode

customizationService.addModeCustomizations([
    {
      id: 'PanelStudyBrowser.studyMode',
      mode: 'primary',
    },
  ])
