Multiple ADC inputs allocated to the same PAD in I.MX RT 1020

Hello community , 

 

I am Naren , I recently was searching for a MCU that suits our application and came across this crossover processor , MCU . I.MX RT 1020 

As per the data sheet it says there are two ADC channels with 16 inputs (2 * 16 = 32 inputs ) , but when i go through the reference manual and pinout  , i observed that there are multiple ADC inputs assigned to the same MCU pad , because of which it makes only 19 inputs available at a time for use , check the excel of pinmux comment if i am wrong and suggest me a solution , since i need at least 30 ADC inputs but only 19 inputs i can use .

 

If you look at the image here , for example PAD GPIO_AD_B1_15 has  ADC1_IN15 and ADC2_IN15  to select from and here i am losing one ADC channel . 

Please share a thought on this .
