How to change alert so that When no one is on-call, notify the next person that starts a shift?

[max-developer]

Hi, we currently have one of our on-call schedules to be office hours only (Weekdays 9-5). However, we are noticing that we don't get notified about alerts that get raised over the weekend. Our expectation was that with these alerts, because no one is there to acknowledge them, they will still be there when someone is eventually on the roster at 9am Monday but apparently that is not the case. (The alert is in the list of alerts, but it doesn't page anyone). 

Is there a way to ensure that the person that gets rostered on at 9am Monday will be notified of any alerts that were triggered over the preceding weekend (period where no one was on-call)? 

Thanks
