This is pretty direct.
Area owners should be able to assign a particular room within the same area or sub-area as the destination where idle/sleeping users (only) are swept to.
(Direct sweep of awake user should be sent home however.)
This would allow sleeping/idle characters to be placed in a room which makes more sense ICly upon disconnecting rather than evicting them fully from the zone.
Additionally, owner customized text would allow things to stay a bit more on theme for room occupants that get blasted with the idle/sleep sweep.
