Option for single alert

Would it be possible to add a check box or something like that on the screen where you create a flight alert that makes it so the alert is only valid for the next landing of that particular flight and then it gets erased?

When I have to pick someone up, I make a cell phone text message alert for their flight but then often forget to delete it later in the day when I get home and then end up getting another alert later in the day or the next day etc…
