Agreed. But at this moment, there is no automated queue, so the option doesn't exist.
You can't do it in minutes right now, though. And if you're legitimately taking hours to find a group, you're out of your mind. I don't spend more than 5 minutes applying before I take a break and run an M+ or do some WQ or something. If you're taking that long to find a group, make your own after 30 minutes.
