You can use the Travel Group feature in Step 5:Publish of a Trip, to send multiple copies of the same trip to different travellers.
Although the Bookings and Documents will be the same across all of the groups, the Journal (available in the mobile itinerary) is only collaborative for travellers within the same group. You can also publish Trips at different times to different groups.
This feature is useful when you have scheduled trips/tours with multiple travel parties - you can manage all the bookings and documents in one place and add new groups of travellers as they sign up.
Creating New Groups
1. To create a new group, click on the '+ New Group' button.
