Yes, it is possible to add different roles to a joint Billetto organiser account. Here's how:
1. Navigate to "Your name" in the top right then click on "Profile Overview"
3. On the left-hand side in the "Organiser" section click on "Role Management"
4. Click the "Add" button to the left. 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.)
5. 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.
