How to show Current logged in user in Cost Center tab

I have several VMs and managed by VMM, but I can just see whether the VM is running or not, I cannot see the current user of the VM,  I can get the logged in user name by powershell: Get-WmiObject -ComputerName "computername" -class win32_computersystem | Format-List username

this is very inconvenient for me, I want to show the current logged in username in the tab such as cost center, so I can see the logged in user to avoid reboot or shutdown the VM in accidently

Could someone tell me how to do it? Thank you very much!
