FEZ Pico pins

I am looking at the FEZ PICO image ( fez-pico-pinout.pdf (ghielectronics.com) and I notice that PA4 is not called out as an analog input. The schematic show PA4 as ADC9 and DAC1. Is there any significance that it is not shown on the PICO image where other ADCs are shown?

PA4 can be DAC1
PA5 can be DAC2.

Same for all SITCore.
