How to log SSH Version and exchanged Algorithms with SSH Inspection

Is it possible with FortiGate security profiles to log what SSH Version is used and which algorithms are negotiated on a ssh connection? For Https connections it's possible to see the TLS version with normal certificate inspection and additionally the exchanged algorithms and parameters when using Deep Inspection. But for SSH I did not figure out how to get the exchanged algorithms and SSH version.

I tried SSL/SSH inspection with DeepSSH inspection and a SSH-Filter profile with all possible logging enabled. For my test policy all traffic is logged. I also applied an application control profile with SSH monitored. All I see in my logfiles is that there is a connection - and with SSH Filter enabled e.g. which commands where issued.
