that probably won't work either, since a custom field would need to be updated and we'd have to find a way to update that en masse depending on conditions.  too bad.  even being able to import a list by system name into a session group would work

Also, how do I unclose a case?  this is not the answer

even putting all of the machines into a session group doesn't work unless we can somehow import the list to create the session group

yeah, that doesn't work in this case.  having to manually select machines when you have over 100 (in this case, 230ish out of 2000), is not efficient.  being able to query a list of systems and running the command for each would be much simpler.  powershell can do an import-csv and then a foreach command, we need something similar here
