How do you set a calender reminder to vibrate and sound off more than once

How do you set a calender reminder to vibrate and sound off more than once? I want it to keep vibrating and keep sounding off until I turn it off much like in the manner you would answer a phone call to stop the phone from vibrating and ringing. Otherwise setting a reminder is useless because it will only vibrate and sound off once. Does anyone know how to adjust this or specific calender app that will do what I'm asking?
