[otrs] Auto Close Timer Setting

OTRS List; Is there a setting somewhere to reduce the timer for an auto-close? Can the timer be set on a per-queue basis? It's possible that I'm going about this in the wrong manner... I'm setting up a new deployment of OTRS. I would like to set a goal of completing and closing "routine" requests within 2 hours. Currently, I have a queue for routine requests. I would like the auto-close to close tickets in this queue within 60 minutes of setting the auto-close. Would this be better accomplished with Services and SLAs? Thank you, Dominic L.
