SPI without Pin 10

thanks for the quick response. So I need a little more help.
right now I have my radio on:

10 CS
11 MOSI
12 MISO
12 SCK

are you saying that I can
a) also connect 10 to my shift register (clock)
b) connect the Latch Pin to 8 and the
c) Data pin to any open pin,

then toggle to pin 8 (data2) push out the values and toggle back to (data1)

Sorry, but as you can tell, I am not keen on these things overlapping. My radio configuration is inflexible that is why I'm asking.
