Dismiss a roster group to delete it permanently. Its itineraries and bookings stay exactly as they are. Dismissing can't be undone.
How to dismiss a roster group
Click Trips in the left sidebar, then click the Roster groups tab.
On the group's card, click Dismiss.
Confirm.
The group is removed from every list, and its itineraries become ungrouped. Itineraries and bookings are never deleted.
If you dismissed a group by mistake, create a new one with the same itineraries.
