How to setup ADC DMA to synch with timer? STM32F4

I'm trying to setup 3 ADCs to read on a timer tick. On the STM32cube the timer can be set to "Output Compare" to a single channel. And the ADC's can be set to external trigger conversion on a "Timer Capture Compare # Event" Finally in the specific settings after a timer has been enabled, the timer can have a trigger event selection. If i'm trying to synch 3 ADCs to all write to separate buffers, what settings do i need to achieve that ?
