For each Account, we can enable or disable the notification rules but for the technicians, this option doesn't work, the same configuration is applied globally.
The reason to have this option is:
A. imagine that you want to enable a notification to send an email to the tech A and tech B when a new ticket is created for the Account A;
B. Now you want to send a notification just for the tech C when a new ticket is created for the Account B;
Currently, we are unable to do this configuration.
