STM32F207 DMA ADC Read with pin state change

Hi, is it possible to have the pin state changed during ADC DMA Regular Simultaneous mode so that the pin that has been read is set to OUTPUT LOW while the one that is read is INPUT?

The current otherwise leaks through the other open analog PINs in my application and the PINs aren't independent anymore. 

I.e. I want to read 24 analog ports (or as many as possible) in sequence using DMA with only one open at a time. It currently works but I need to have all ports open.
