At the moment SEPM has the ability to set a delete machine after being offline for so many days but this works on an overall SEPM basis. It would be useful to have this on a group basis for estates that have a citrix based setup that reboot from a cloned image that replicate from a VM and create multiple machine instances.
This way you could have the rest of the SEPM say delete machines for example after 60 days of being offline and your citrix machine group set to delete offline machines after 1 day of being offline. This way reporting would be more accurate as it would as it would not be taking the offline duplicated machines into account and also using up licences on the SEPM.
