The accounts lists that are displayed by default for all Engagio users are defined in Settings -> Journey -> Journey Settings by the Engagio Admin.

But each user has the ability to modify the admin defaults by searching and adding account lists of their own choosing to the dashboard.

The user can then choose to go back to the admin defined account list anytime.

The user preferences are sticky - so even if the user leaves Engagio and then comes back again their user defined accounts lists will showing on the dashboard.
