amusing STM32F427IG controller with STM32Cube_FW_F4_V1.10.0software. I need to know if I can program different sampling rate for differentchannels of same ADC?

Problem statement: In ADC1 need toscan three channels CH1, CH2 and CH3 all at different sampling rates CH15000SPS, CH2 50000SPS and CH3 1000SPS. Can this be done?

Presently I am able to scan them atsame sampling rate using Timer2 to set sampling rate, and DMA transfer toSDRAM. But would like to know if scanning at different sampling rate possible?If yes then what mode to use and what will be the settings?
