For more information on creating groups and adding users to groups, please refer to the User Groups page.
Once users are assigned to the appropriate group, you can select the group from the "Users" drop-down menu on the Schedule page:
Likewise, you can use the saved search to view the selected group. To do this, you will need to create a new saved search. For more information on creating a saved search for the Schedule page, please see Schedule List page.
Once you create a saved search, you can mark it as the default so that way your preferred group is always displayed on the Schedule page.
