Is automatic Wake On LAN possible with DD-WRT?

Is automatic Wake On LAN possible with DD-WRT?

I might be thinking the wrong way to solve this problem. If there's a better way, than tell me. I want to be able to allow my home server to sleep when it's unused, but to automatically wake up when it's accessed. My household doesn't follow a set schedule due to people working different shifts, so I can't schedule an optimal sleep/wake cycle for the server
