Downtime Scheduler

Is it possible to use the downtime scheduler on a monitor in a specific device or is there another way to
go around this problem?
If it was possible to create a dummy device i could add the url monitor i want to that device and include the device
in the scheduler, but it seems its not possible to create a device that doesn't exist.

The url monitor option under admin would be a solution because its possible to add those to the scheduler,
but on the other hand i can�t connect any notification profiles to the monitor and then its useless.

Is there any solution to this?

Thanks in advance
