Possible to see which windows user is logged in from 'Computers' tab?

Is there any way for me to see what user is logged into windows on my computer list without logging into the dashboard?  Can I find it somehwere in 'properties' or maybe by one of the sortable fields?

Sorry if it has been asked before but when I  search for the issue I just get info on how to check the logmein users.  I want to know who is locally using each machine.
