Partial Reward seats availability

I understand while reward seats are very limited but say for a route, there is 1 reward seat left and we get to select 2 and more. I create an alert for 2 seats. If there’s 1 available out of 2, is it possible to get an alert for that only? I mean at least I can secure 1 seat out of 2 and can possibly wait for another when it’s available.

Thanks!
