Query job history for TSX servers from MSX server using TSQL
Whenever you want to see what SSMS is running, you can always fire up a Profiler/Extended Events trace and filter on your login.  

Doing this from MSX master and viewing a Multi-Server's job history gets you this query:

SELECT null as instance_id, 
     sj.job_id,
     job_name = sj.name,
     null as step_id,
     null as step_name,
     null as sql_message_id,
     null as sql_severity,
     sjh.last_outcome_message as message,
     sjh.last_run_outcome as run_status,
     sjh.last_run_date as run_date,
     sjh.last_run_time as run_time,
    sjh.last_run_duration as run_duration,
     null as operator_emailed,
     null as operator_netsentname,
     null as operator_paged,
     null as retries_attempted,
     sts.server_name as server
  FROM msdb.dbo.sysjobservers                sjh
  JOIN msdb.dbo.systargetservers sts ON (sts.server_id = sjh.server_id)
  JOIN msdb.dbo.sysjobs_view     sj  ON(sj.job_id = sjh.job_id)
  WHERE sj.name = 'MULTI_SERVER_JOB_NAME'
