Greetings everyone

I was wondering if there is any possibility to add multiple Requesters to a single Ticket. We often have Tickets, which affect more than one of our customers. Therefore, this would be a great option. I know about the function with the "E-Mail Ids to Notify", however this only accounts for the messages, which are sent manually. System Notifications from the Request Life Cycle are not sent to the E-Mail Ids to Notify or is there any way to achieve this?

Thank you very much.
