Commented Unassigned: All Unassigned Service Requests script needed [11252]

Hello, I would like to write a script to pull all the unassigned service requests that were created 12hrs prior to current date. I need to be able to filter on specific support groups. It appears easier to do this for incidents but because there is no get-scsmservicerequest cmdlet, I am at a loss. Thanks

Can't seem to edit comments :(. But forgot to fix the AddHours value, it's of course suppose to say -12 and not -400.
