I'm really still discovering OTRS (a trainee in a IT department) so please bear with me

Is there a way to manually escalate a ticket in OTRS ?
I've read the doc on how to use the generic agent and set up a task running every X minutes/hours as well as setting up escalation times in the queue area, but i need a way to make an agent able to simply escalate a ticket as he wishes, especially from one agent to another.
What would be a good way to do that, if there is any ?
Thanks, and best regards.

[edit]: might have been better to post into the Help::Configuration
