It's not possible to mention the unique names on each ticket, but it is possible to ask for unique names for each ticket. This can be done by adding questions to the order process.

  1. To make sure names are only asked for entrance tickets (and not for instance for locker tickets), make sure to only add questions to the tickettypes for which you need a unique name. If there are several tickettypes for which you need a unique name, make sure to add the extra question for EACH tickettype. 
  2. To do this, go to 'Questions' and then under 'Configuration' select 'A specific ticket' and 'For each ticket' and make sure the question is required.
