E-mail alert to different people through the day

[SecurHost]

currently have a simple ping setup to a device.I would to know if it is possible to have a e-mail sent to different people base on the time of day if ping fail.
Example:
Monday 6am to 12pm email "person A"
Monday 12pm to 6pm email "person B"
Monday 6pm to 6am email "person C"

Add 3 "send e-mail" actions into alert profile, set different schedules to each action using "Time restriction" action option.

Time restriction
Schedules can be applied to actions the same way they were used for tests. With schedules, actions can be customized per time of the day. For instance, an action profile can be set up to page both the IT manager and the network administrator during regular office hours, and to page the administrator alone the rest of the time, while doing nothing else but writing to the log on weekends. To make this possible, simply check the "Time restriction" option and select an appropriate schedule.
