Send Contract expiry notification before 90 days , 60 days, 30 days and 0 days

Is there a way you can send notifications 90 days before contract expiry then 60 then 30 and then 0 days.

We know at contract type level there is one notification. Can we use the BPM reminder setup using the ContractExpNotificationHumanTask object.

Suggest any other way to do it, other than reporting.
