Duplicating a project is useful when you want to create another event for the same client with the same inventory or venue. After duplicating the project you can still go in and edit it to change the time and date.
To duplicate a project, open the project itself and select the more icon.
In the provided drop-down menu select Duplicate Project
The changes can be seen in your projects menu.
You will notice this will create a conflict since both events are using the same logistics and inventory at the same time frames.
You will then change the dates of the new duplicate project to reflect the correct dates for the following year. This will get rid of the conflict.
