"It would be great if the reschedule meeting screen had an option to reschedule the meeting to right now and start the meeting with one click. Right now I have to reschedule the meeting and change the date and time to the correct range and then go back in and click start now so it is a lot of clicks. "
I think adding "start now" to the dialog that pops up when you click "Reschedule meeting" might be the way to go. That would be two clicks.
