Netview Maintenance Mode?

["Paul Maine Jr." <paulm@msicc.com>]

Occasionally, when we are troubleshooting a network device, the network
device repeatedly goes up and down. Is it possible to put a monitored device
in a maintenance mode for a specified time window. During this time window -
netview would ignore the device. If Netview does not have a direct way of
doing this - is there a means to script it?
