Find a way to call multiple numbers at the same time by dialing one "group number"

Hi, is there a way for me to call multiple numbers (up to ten) by dialing one group number? I imagine i can add these ten numbers into a group. And then instead of dialing one after the other, i can somehow dial one "group number", and then RingCentral can dial those ten numbers for me. In my case, we don't have to conference/talk. I just want to wake them up for system testing around midnight. :-) Thanks, Lei
