Is there a way to link Nav 2015 Session ID to SQL SPID?

Hello,

I am wondering if there is a way to link a Nav 2015 Session ID found in Active Session table to the SPID of the session in SQL (found by running the sp_who2 stored procedure for example)

The sp_who2 command will let me identify what session is causing blocking, but it won't say anything about the user as it only shows you the service tier information. I would like to be able to identify the session and the userid/computer name of the blocker when a blocking issue occurs and if I could map SPID to Session ID then this would allow me to do that

Is there a way to do this?

Thanks
