Notification only when price reaches a new historic low

Currently I have my notification set to “All time low”. However, I still get notified when the game reaches that price again (“Matches previous low”).

I’d like to only get notified if it reaches a new, lower price.

The logic is this: I was already notified about the game reaching price X, but I didn’t want to buy it for X, so in the future I would only want notifications if the price is lower than X.

An automated way of finding the actual price I’m willing to pay for the game, so to speak. Could either be global (when the game reaches a new historic low, send notifications), or per user (when the game reaches a new low that the user hasn’t been notified before, send notifications to that user), the former is probably a lot easier to implement.

You could set a threshold manually, for example if all time low was $10 you could set “Under $9.99” as a threshold. Or whatever you actually want to pay.
