Hi @curtgran,  as @fk319 said, you could use the transaction command, but this is a very slow command, so I hint to use it only if you haven't any other solution.  I usually use stats command correlating events by the common key (in your sample AssignedIP and src_ip).  Something like this:  (search_one) OR (search_two)
| rename src_ip AS AssignedIP
| stats values(username) AS username earliest(_time) AS _time values(dest_ip) AS dest_ip values(traffic) AS traffic BY AssignedIP  I listed all the fields you have, obviously you can use only the ones you need in your use cases.  ciao.  Giuseppe
