SMA connector on CW305

In my project, I need to use the SMA connector as an output of my design. I want to know if it is possible to use those SMAs that are available on the CW305 board as an output of my design, or if they are only usable for clock and power measurement.
Thank you in advance for your help.

The schematic has the answer (two of the SMAs connect directly to FPGA pins).
