Need one liner for Managing SCCM Client Site Code

Could someone plz guide me to create a one liner PS Command for the following 3 commands?

++++++++++++++++++++++++++++++++++++++++++++
$a = New-Object -ComObject Microsoft.SMS.Client
$a.SetAssignedSite($a.AutoDiscoverSite())
$a.ResyncPolicy()
++++++++++++++++++++++++++++++++++++++++++++

The reason why I am looking for a one liner is because I want to avoid creating / updating a OSD package for the script.

Thanks in advance.
