Connection Server Custom Session Timeout

Our View Connection server has a global session timeout of 18 hours for our PCoIP connections.  We have a pool of VMs needs to run jobs that can take up to 72 hours to process. Is there a way to override the default session timeout for a particular pool or group of users or PCoIP terminals?  Everything that I've seen in the documentation leads me to believe that there is only one value for the session timeout and it is a global value for all sessions on that View Connection server.  Any help is appreciated.

Thanks,

Jake
