Can some of the pins of a peripheral be remapped while others stay at their existing AF location?  I noticed in reference code on the STM32F107 that appears that some of the pins are remapped, but not all of them.

I want to dynamically remap the SS pin for SPI3 to drive two devices, can this be done without moving the MISO, MOSI, and SCLK pins?

What does the Reference Manual suggest?

Drive the Chip Select as a GPIO, then you can use any pin(s) you want.
