STM32F37x DMA SDADC + DAC same DMA Channel

Dear Community,

I am trying to use two peripherals (STM23F373) SDADC1 and DAC1_1 having the same DMA access channel: DMA2_Channel3 (STM32F37x reference page 164).
Due to a synch problem I want to use the DMA in normal mode thus I need to reset the DMA counter after each TC interrupt and unfortunately I can’t use the 12 bit ADC since it produces some strange spikes its conversion result (this topic is already addressed here but without solution). 
  
Is there a way to distinguish from which DMA memory (assigned to the SDADC or the DAC) the DMA_TC interrupt was fired ?
