Remove TinketHook from subject in Ticket Notification

[zerozone74]

Hello,
I need remove [ticketHook#0000] from subject in sending email from Ticket Notification (applies to one notification only).
Do you have any idea?

How will you be able to connect answers from customer to your ticket without it? Body?

Check manual:
https://doc.otrs.com/doc/manual/admin/6 ... icket.html

Use option none.

Ticket::SubjectFormat
The format of the subject. 'Left' means '[TicketHook#:12345] Some Subject', 'Right' means 'Some Subject [TicketHook#:12345]', 'None' means 'Some Subject' and no ticket number. In the latter case you should verify that the setting PostMaster::CheckFollowUpModule###0200-References is activated to recognize followups based on email headers.

This setting can not be deactivated.

Default value:

--- Left

You write the obvious.
That is why I ask because I need to have full control over the topic - I have to send a notification with a specific topic and that's it.
TicketID is in content and this must be enough.
If I change Ticket :: SubjectFormat it will apply to the whole system and I need it with only one notification.
