Reference are too big = not used by users in their communications by phone

Example : my ticket number is xx xxx xxx is not user friendly             

Add a Custom Field Incremental numeric value linked to the position of the ticket "In this category / In this section" (2 options)

B.Each parties can see directly quantity of tickets in this category/section (psychologically it can help to understand the degree of recurrence of the same type of ticket)

   By this way, the service can understand easily if they need to adapt something if he hear 999 = a lot of tickets of this type

                         The user can understand "I'm alone to register this type of ticket = service may be slower
