How to trigger an ADC conversion externally with TIM1 event

My project uses STM32F103 MCU. I want to have TIM1 event to trigger the ADC conversion. However, the peripheral reference manual states that only TIM1-CC1,TIM1-CC2 and TIM1-CC3 envents can trigger the ADC. I need to trigger the ADC at either underflow or overflow event. Any suggestions?

Thanks.
