Sending a ticket tracking a third person

We actually can add more people to each category.

In the ticket notifications, we can associate with whom we wish to send an email for information.

However we can not choose who is particularly address a tracking ticket.

Some element followed by ticket should not be communicated to everyone. We are obliged to make an email for a single point of contact through our mail client in this case so there is more monitoring in the GLPI ticket order to achieve the overall monitoring from GLPI is it possible to add the monitoring tab, the option to choose a contact GLPI to address a single track.

Example: A user makes a request for assistance. An exchange takes place between the applicant, the observer and the technician. If the technician has to ask a question has an outside party without the applicant and the viewer is informed. (Problem X internally and technician made a special request to an external service provider) hope I was clear on my explanations, I remain available for any possible discussion, thanking you
