Automatically log into the webex call

I hate being late to meetings. The worst is when I'm waiting for a call to start in 5 or 10 minutes, then I get distracted working on an email then I realize that the call started 2 minutes ago. It would be great if I could open webex, and click a button that said something like, "auto join at the meeting time". Then I automatically join the call at 9:30 when the meeting time starts. I don't necessarily want to join earlier and small talk with people in the room, I want to join right at the top of the meeting time.
