I don't know of a way to do that. When I need to have an escalation run only once I will either set it for an interval of 99 days (if I want it to run immediately) or for a specific day of the month and time. In either case you must go back and disable the escalation but that will give you 99 days or one month respectively to do so before it fires again.
