Setting for Unique Ticket number in group registration

I've been unable to find a setting to enable unique ticket numbers when a group registers multiple people.  For example, John Smith and Jane Doe register together.  I need John Smith and Jane Doe to have their own Ticket IDs i.e. John Smith: 624-100; Jane Doe: 624-101.  This is happening with individual but not with group registrations.

We're on Joomla ‎5.2.1 and Events Booking 5.0.2

Hello

Unless there is something special, ticket number should be unique. For this special issue, please submit a support ticket so that I can check it directly on your site
