Yes, it is possible to add different roles to a joint Billetto organiser account. Here's how:
1. Click on your "Account Overview" - the icon to the left of your profile picture in the top right corner of the screen.
2. Click on "Role Management" in the left sidebar.
3. Click the "Add" button to the right. Fill in the name, email address, and the type of role you want the person to have. Here's an overview of what permissions each role has.
(Note: It's currently not possible to add already existing Billetto users to new roles.)
4. Click "Save." The added role should now appear at the bottom of the list.
Note: The added person will receive an email and be able to create a password for their role.
